So you can easily build and integrate this circuit in the place of the EGS002 sine wave driver board. SO how can we create this SPWM signal? Well, with the Arduino, in the code, we make two pins to be PWM pins by setting some registers, TCCR1B and TCCR1A. My total load is 160W. I therefore need to modify the secondary by removing some windings until I get 9V output. To get a minimum inverter facilities from this practice we have added a mosfet driver part and a transformer as well. Arduino: Arduino Uno R3 is used to generate control signals for MOSFET driver using SPWM ( sinusoidal pulse width modulation technique). The following circuit is a Full-Bridge MOSFET circuit for the EGS002 SPWM Inverter, and I used it in the Arduino Uno SPWM Inverter experiment. The question is will the transformer then be able to cope with a 160W load.
