this is for 10khz switching. during simulation in proteus it is giving some pulses during off time as well . i dont know why it is giving that extra pulses.
i had developed it on breadboard as well in DSO it is giving out similar pulses during off time.
images are attached kindly help me . im a newbi in this area.
this inverter ckt is not giving output in proteus simulation but i had shown the pwm output from pic and driver but when i tested those without mosfet on bread board pwm from pic was giving unwanted pulses during off time as shown in simulation output . and the driver output got me all confused the low side is boosted to 12 v but high side is approx 5-6 v. low side ias some how similar to pic pwm out put but not the high side it is like all time high .
power supply used is rectified and filtered ac from 220 v supply sepped down to 30 v and rectified with 3 different ckt for 5v , 5v and 12v.
while simulating this circuit in proteus it gives some error im unable to understand how to rectify this the circuit and ther error is attached. plese tell me what is the error and how to rectify this the input to the inverter h bridge is 20v dc ir2110 vcc is 15v dc
hello
please change bootstrap diode with uf4007 or equivalent. bootstrap capacitor is also too large for high frequency usually small value is recommended try 2.2uf.
i am not able to find uf4007 in proteus.Can u plese suggest some replacement for it also changed the bootstrap capacitor to 2.2uf but still same issue.

hi
i got uf4004 n im getting result for few min but then it gave this error and stopped
