    Hello,if you could advise on how I can reach 15V from the PIC it can be helpful,I would like to control a full bridge made using IGBT Dual Modules but there are not working perfectly,I am getting only 10Vac while my H-bridge is at 48v so I am judging that the IGBT are not fully turned on,could you advise on how I can proceed so I increase the VGE?
    I ma using PIC16F1936 and IR2110 but at the output of the driver Ho has 6V and LO has only few mv around 600mV

    My circuit was implemented referring to http://tahmidmc.blogspot.com/2013/01/using-high-low-side-driver-ir2110-with.html
    Please help

    What voltage are you using for Vcc on the ir2110?

    This sounds much more a probem related to the magnetics scope ( namely, transformer windings ) than IGBT driving itsef.

    On the IR2110 the VCC is +15V on pin3 and on pin9 the voltage is +5V.

    Whould help a lot if you can attach the circuit schematic.
