I have reduced the length of wires and i have also placed a 470 uF capacitor across the bridge.
The ringing is reduced partially for the positive cycle of square wave (output voltage of the inverter), but the ringing remains for the negative cycle of square wave.
Why there is no decoupling...
When i connect a resistive load at the output of the inverter, the ringing reduces.. So i am not getting the reason for the ringing when inverter output terminals are open
Hi,
Thank you for your reply..
I am measuring the pulses at the gate and source terminal of the switches.
Duty cycle is 50% to 20%
I am measuring inverter output voltage without load.
i am attaching the images of gating pulses before and after applying input voltage to the inverter,, inverter...
I am using IR2110 driver circuit to drive the 100 kHz H-bridge IRF640 MOSFET switches. But as the input voltage to the H-bridge increases (about 25 V) the pulses gets distorted. I have attached the driver circuit. Please help me to solve the problem.
i have attached the circuit diagram below
