I am working on grid contected inverter for my final project for this I'm making h bridge but low side of mosfet driver is working properly but there is no output on high side can any one help me with this..
Where's the rest of your circuit? HO won't rise to the correct bootstrapped level unless VS gets pulled up by the upper MOSFET. With the circuit as shown I would expect HO to be pulsed at 12V, not a constant 5V.
thanks for clearing me. i have practically try complete bridge but its not working. that's why i want to separately check the mosfet driver what type and value of bootstrap cap you suggest. and what is the difference between ir2112 and ir2110.
Thanks for suggesting a wonderful blog It clear my all concepts about mosfet driver. Please tell me one thing That I have mosfet driver ir2112 instead of ir2110 can I use it?
