This is two stages inverters

Two stages inverters are inverters that first converts the input battery voltage to 310V - 390V DC using high frequency. This is achieved by switching ferrite transformers EE55 at high frequency 80Khz, power 2KW . The square wave output of the ferrite transformer is then rectified using diode bridge rectifier and filtered using 400V electrolytic capacitors. This ends the first stage of the two stages inverter.

The second stage of two stages inverters works by converting the 310V DC to 220V AC pure sine using mosfet bridge with an control drive circuit Egs002.
