Background and trends of solar inverters

Many of the advantages of the solar inverter, which is safe and reliable, no noise, no pollution, energy widely available, without geographical restrictions, no consumption of fuel, easy to maintain, can be unattended, establishment period is short, the size of random, without erecting transmission line can be easily combined with the building, and so are the advantages of conventional power generation and other power generation methods that fall. With the continuous development of the type of increase in 1000w charger inverter and control technology, the photovoltaic power generation system can be applied to all areas of the national product and related to daily life.
Inverter PV system is an important part of the nature of the power inverter output power quality photovoltaic systems. Modern inverter technology, many different types, can be categorized in different forms, there are several:
(1) according to AC inverter output frequency can be divided into frequency inverter, medium frequency and high-frequency inverter. Frequency conversion inverter makes use of frequency transformers to achieve electrical isolation between input and output. This inverter is a simple structure, reliable operation, but the inverter is bulky, heavy, noisy, efficiency needs to be improved. With the increasing performance requirements of the power supply, conventional frequency 4000w solar inverter gradually transform difficult to adapt to the lightweight, high power density, high reliability requirements. High-frequency transformation is the use of high frequency conversion technology, it has the advantage of small size, light weight, low noise, high efficiency.
(2) according to the number of phases of the inverter output can be divided into single-phase inverter, three-phase inverter and multiphase inverter.
(3) The form of the main circuit of the inverter can be divided into single-ended, push-pull, half-bridge and full-bridge and so on.
(4) by type inverter main switching devices can be divided into thyristor inverter, transistor inverter, inverter FET, IGBT inverter, and so on.
(5) by stabilizing output parameters can be divided into voltage inverter and a current source inverter.
(6) according to the control mode can be divided into transposition PWM control mode and control mode. Transposition control principle is that the two switches full bridge circuit for each leg of the complementary conduction, a phase difference between the two bridge arm switch is turned on, and by adjusting the size of the phase shift angle, to regulate the output voltage pulse width, to regulate the output voltage.

For solar inverters, the input is generally low-voltage DC output high voltage frequency AC output voltage waveform has two types: sine wave and modified sine wave. Pure sine wave power inverter corresponding thereto may be suitable for all types of load, have a good ability to adapt, due to its harmonic content is small, high power quality, so it has good market prospects.
Energy conversion technology development so far, it is no longer an optional back-up device, but the power supply system is an indispensable part. In particular, and combine photovoltaic power generation system that enables independent development of photovoltaic power supply have a broader space. In China's vast central and western areas without electricity, the population density, live in scattered, and has abundant solar energy resources, is very suitable for the development of stand-alone photovoltaic technology. Combining photovoltaic technology and power conversion technologies will be greater development, become an important way to solve the power shortage in the western region without electricity or electricity.

The various components of the solar inverter efficiency impact assessment

The use of solar PV systems more widely, not only in industry, but also began to slowly into the family. How to improve the efficiency of solar power is solar energy development has been plagued by reason. Solar cells and solar inverter itself is connected with the public grid or solar energy efficiency distribution power, solar technology is the key to success.
Solar systems, the solar cell power regulator enables work to maximum efficiency. Whether to adopt 4000w charge inverter transformer, it will directly affect the efficiency of the system. Using a transformer system efficiency will directly lead to decline 1-2%, while solar inverter DC component must be avoided, current requirements must be less than 5mA. The output filter may weaken from the output of the 4000w inverter charger stage generates a current ripple is inversely proportional to the size of the switching frequency of the filter and the costs associated with the inverter. The higher the switching frequency, the smaller the filter size, the cheaper the price. However, the higher the switching frequency, the greater the loss, the lower the efficiency, in order to take compromise, 16KHZ-20KHZ switching frequency, with low noise and high efficiency audio, meet the requirements of the solar inverter.
DC / DC converter is running at 100KHZ switching frequency states or more, the converter operating in continuous mode, which means that the boost inductor current is within the rated conditions will produce a continuous waveform. When the transistor is turned off, the diode is used as a freewheeling diode, the transistor can charge the inductor. That is, when the transistor is turned on again, the diode can automatically shut down.

220v inverters Independent inverter operating characteristics of the PVS

( 1 ) Reliability

PVS from the previous operation , the inverter is one of the main factors affecting the reliability of the system . Since independence inverter typically work in remote areas , if there 3000w charge function inverter‍ are problems maintenance inconvenient , so the first requirement is independent inverter must be safe and reliable operation .

( 2 ) Rated output capacity

In the stand-alone inverter, rated output capacity is also a very important reference factor , which indicates the load capacity of the inverter power . High values ??of rated output capacity inverter can bring more electricity load. In this particular note is that when the inverter is not purely resistive load, the load capacity of the inverter rated output capacity will be less than the value it gives .

( 3 ) inverter efficiency

Inverter improve the level of efficiency of the system and reduce the effective cost of electricity generation capacity has an important impact. Due to the current cost of solar cells is still relatively high, but there will not be much reduced in recent years , so for standalone inverters require high efficiency , Car power inverters‍  especially when low-load power , still has high efficiency, low the load is independent of the load in higher demand dedicated PVS inverters inverter is relatively common .

Therefore, typically inductive load starting , the inverter will withstand large transient power surges . The inverter should ensure reliable starting at rated load , high-performance inverters can be done repeatedly without damaging the starter full load power solar power inverter‍ devices . Small inverters for their own safety , and sometimes requires the use of soft- start or limit start .

For example : UPS power supply inverter , inverter technology inverter technology , special power of inverter technology and power regulator inverter technology, these have been in the form of the product to the market , and by the social widely recognized.

In the small-capacity , low- PVS , the more power 48v to 220v power inverter ‍the device using a metal - oxide - semiconductor field effect transistor (MOSFET). Because at low pressure , with a low on-state voltage drop and high switching frequency, but with the MOSFET voltage increases , the on-state resistance increases . Thus, in the large-capacity , high-pressure PVS , in general, the use of insulated gate transistor (IGBT) as a power device ; in large capacity above 100kVA PVS , in general, the use of gate turn- off thyristor (GTO) as a power device . PVS inverter driver circuit in the main power switch for the gate drive . To get a good PWM pulse waveform , the drive circuit design is very important. In recent years , with the development of microelectronics and integrated circuit technology , have launched a number of multi-function -specific integrated chips , such as : HIP4801, TLP520, IR2130, EXB841 etc., which brings great convenience to the application 3000w charge function inverter‍ circuit design [ 1 2 ] .

With the growing concern for the urban environment , the development of electric cars got a rare opportunity. In urban traffic , the electric bus due to the large carrier , comprehensive benefits , become the object of priorities. Electric buses were powered by a three-phase AC motor, because the motor power, three-phase inverter device needs to withstand effects of high voltage and high current stress , high dv / dt and severe electromagnetic radiation , and the need for good cooling.

The use of multi- series structure of power inverter is a single device reduces voltage stress , reducing the device's requirements; reduce the dv / dt value , reducing the electromagnetic 24 volt power inverters‍ radiation , heating devices are greatly reduced ; due to output increase the level of species , the control performance is better.

Multi series inverter suitable for high-power electric vehicle drive system. Using multiple tandem structure , a plurality of batteries connected in series can reduce the risk that will reduce the switching device and reducing the stress of electromagnetic radiation. But the number of batteries needed increased 2 -fold.

Multiple tandem structure of the output voltage vector species greatly increased, thus increasing the flexibility of the control and improve the accuracy of control ; motor while reducing the fluctuation of the neutral point voltage . In order to maintain the balance of each set of battery power , the need to ensure a 24v bypass inverter‍ consistent runtime battery discharge time. Through the bypass mode , the flexibility to charge the battery pack , regenerative braking torque can be controlled.

With the development of resonant switching power supply , thinking resonant converter is also used in the inverter power supply system , which constitutes a resonant inverter efficiency . Solar power inverters‍ The inverter is the use of a zero voltage or zero-current switching technology in the DC / DC converter , and thus can basically eliminate switching losses , even after more than 1MHz switching frequency when more power efficiency is not significantly reduced. Experiments show that : in the same operating frequency , the resonant conversion loss comparable non-resonant mode conversion was reduced by 30 % to 40 %. Currently, the resonant frequency of the power supply of up to 500kHz to 1MHz.
