Can I drive a Full-Bridge with PWM1H1 and PWM1L1 signals of dsPIC33 and IR2112?
I need to get 220V AC 5kHz from the Full-Bridge output. Due to low PWM resolution issue in PIC18F, I am preferring to use dsPIC33FJ32MC204.
My PWM frequency will be 100kHz.
I need to get 50kHz Sine signal from the SPWM.
So, can I drive Full-Bridge (4 N-Channel Mosfets) with PWM1H1 and PWM1L1 signals using 2x IR2112?
I have not yet started writing the code.
This much circuit I have designed (check the attached PDF file).
The voltages of graph 1 and 2 doesn't look right. Why?
