220 volt power inverters Principle Power Inverter

Using a thyristor circuit to convert the direct current alternating current, this corresponds to a reverse process of the rectifier, the inverter defined. For example: Pure sine wave power inverter‍ Application thyristor electric locomotives, so that when the downhill braking DC motor as a generator to run the locomotive's potential energy into electrical energy, trans go to the AC grid. Another example is the operation of a DC motor, to make it quick braking, the electric motor as a generator also allows operation of the motor kinetic energy into electrical energy, anti-delivered to the grid. 

The inverse DC into AC inverter circuit circuit called. In certain cases, the same set of thyristor rectifier circuit not only for, but also as an inverter. 

Converter in the inverter state, if the inverter AC side connected to AC power, the inverter converts DC to AC power with a frequency counter to go, called active inverter. If the change is not the AC side current grid connection, but directly to the load, which is a frequency inverter converts DC or AC adjustable frequency supplied to the load, then called passive inverter. AC frequency converter uses this principle to work. Except for the active solar inverters‍ inverter DC reversible speed control system, but also for the exchange of spare lines rotor induction motor cascade control and other aspects of HVDC.
