hi
I am driving a motor using H bridge configuration. It contains IRFP450 and to drive this 4 NMOS i use gate driver IR2110.The drain of the upper two NMOS connect to 312DC and the voltage at its gate is 15V.As the gate driver IC start giving pules to the MOS, motor start revolving but at a very slow speed..I then check the voltages at the gate of and sources of the MOSFET. The MOS which is connected to the ground gives correct voltages at the gate and source but the MOS which is connected to the VCC gives 46V at the source and 45V at the gate..i didnt understand that voltages at the gate and source of the upper MOS
Plz help me in solving that issue.
Thanks.
