As an update, I was able to find the problem seems to be with the sine wave data that i have been producing. Rather than reducing both the amplitude and the offset by X percentage I tried just reducing just the amplitude. Doing so now produces clean sine waves as expected for the reduced PWM...
Thanks for your replies. I will post some more details of the circuit tomorrow and of the code when I fire up the computer.
I am using an arduino nano (atmegga 328), using timer1 in 10 bit mode on pins 9 & 10. I am using a table of 800 values for 1 full cycle of the sine wave. 800, as it is...
Hi,
I am new to this forum and hope somebody can point me in the right direction with the problem i am having as I build a pure sine wave inverter.
I am using PWM and its complement at 20kHz to drive an HIP4082 Mosfet Driver and H-Bridge made out of IRF3205 Mosfets. The output then feeds a...
