  1. Consider the circuit in the figure, which consists of an ideal MOSFET and an ideal diode. The gate-source voltage applied to the MOSFET is illustrated in the figure. Find the average voltage across ' a ' and ' b '.

Explanation & Steps

First of all we need to determine whether MOSFET is ON or OFF for VGS = 10 V and 0 V. Diode current and voltage across MSFET can be dtermined for these two conditions. For one cylcle, average value of voltahe across node a and b as well as diode current can be determined. Conduction loss across diode will be multiplication of diode volatge abd average diode current in given time period.
