A relatively simple 1000 watt pure sine wave inverter circuit is explained here using a signal amplifier and a power transformer. It is also used to drive mosfet connected with trnasformer. Latch is immediately set providing the fastest turn off signal to the outputs.
Sg3525 is used control output voltage of inverter by feed back voltage control method.
It worked quite okay but the problem is i tried to adjust the frequency to 100hz base on your explanation but the minimum i could get is 165 2hz. Both mosfet is used as low side connection. If you are using spwm as the input then please replace the lower bc547 with bc557. Dc dc converter using push pull topology.
