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

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