PART3

Bootstrap Capacitor Design:

From the application notes of the HIP4081, we studied that the bootstrap capacitor must be greater than the ten times of the gate to source capacitance of the MOSFET used in the bridge.

Qgs = 12.3 nC 

Vgs(min)= 2volt 

Cgs = Qgs/Vgs = 12.3/2 = 6.15 nF

 So bootstrap capacitor > 61.5 nF 

We used a value of 200 nF.
