good day everyone
I'm having a problem not exactly sure what the cause is but I suspect its ground plane noise. I'm using a PIC to generate a PWM signal to my power circuit at about 60 kHz. Whenever I push the input voltage past 50 - 60 V the system doesnt switch properly. up until 50 V it works perfect. I suspect the PWM signal is getting distorted. I'm using a half bridge configuration and above 50 V the output waveform decreases and gets distorted. Please if anyone who has encountered a similar problem please help me.
Thanks
