Hi Everyone,
I have designed a H-bridge circuit and I made a prototype board for which I have also attached the schematic of the circuit.
The board is designed for 300 V DC operation. But i started to test it with 48 V DC(safer side). I tested it as two half bridge circuits seperately.
The resulating 48 V square wave has peaks as the frequency is increased.
At 5 KHz , I don t have any peaks but at 30 KHz I have these voltage peaks.I have also attached the oscilloscope readings.
Could someone please help me out.
I am so exhausted.
I tried increasing the value of MOSFET gate resistance ,
but it ain t seem to work
Please help me out.
Thank you guys.
