I (qbs), Quiescent current for high side. Following are the the values of the parameters that I was able to find: Qg, Gate charge of High Side FET 63nC.

You cannot charge the bootstrap capacitor while the upper switch is ON ( the voltage from the switch is going to Vs and while the switch is ON the voltage on the cap is HVcc (500-600V) voltace on the capacitor value at which it is charged to. I'm going to be using two IR2113 ICs to control each side of an H-Bridge (intended for an Inverter application.) From the application note, the expression to find the bootstrap capacitor is as followsĬ > \frac\$. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as dielectric. From the application note, the expression to find the bootstrap capacitor is as follows. ir2110 application notes I think that you have mixed some things in bootstrap operation.
