Principle of inverter power supply
Jan 13, 2017

Reverse direct current alternating current circuit called the Inverter circuit. In certain situations, with the converter can be used as either a thyristor rectifier and inverter.

Converter when the inverter, if receiving AC power supply the AC side of the inverter, reverse into direct current with the frequency of the AC anti-sent to the power grid, and is called the active inverter. If the converter is not connected with the grid on the AC side, and directly to the load, into a direct current reverse frequency or adjustable frequency AC power supply load is called passive inverter. AC variable-frequency speed control is the use of this principle. Active except for inverter DC reversible speed governing system, also used to exchange spare wire rotor induction motor cascade speed and high voltage direct current transmission and so on.
