I want to generate AC from DC(an inverter). I am giving Bipolar SPWM(sinusoidal PWM) to H-Bridge. At output I am getting AC signal but with noise. I have attached required screen shots.
schematic of H-bridge.
Output between Q2 and Q4 emmiter terminal.
Output between CN1 and CN2.
Zoomin output.
Please help in resolving this issue.
