Innovation in the inverter

There are four types of power conversion: ① DC-DC converter, it is converted into a DC power to another DC converter energy; ② DC-AC converter, it is converted to DC power to AC power inverter This converter device called inverter, ③ AC-DC converter, it is converted to AC power to DC power converter; ④ AC-AC converter, which is a form of communication to another AC power conversion The power converter.
Does not appear before the inverter, DC-AC conversion by the DC motor is an AC generator to achieve this combination is called rotary converters. With the rapid development of power electronics technology, successfully developed a high-power switching devices and integrated control circuit, the use of semiconductor technology can complete the DC-AC conversion. Such conversion device called a static inverter, commonly referred to as an inverter refer to static inverter. stationary inverter and rotary converters compared to its excellent electrical properties, high efficiency, high reliability, light weight and small size. Recently, the development of battery materials emblem ascendant, ultra high-power DC-AC converter will replace the rotary converters.
