Question 3:
A 2N6755 Harris n-channel MOSFET has a de supply voltage of 60-V, and a load
resistance of 6-2. With a gate-source voltage of 10-V, the on-state resistance is 0.2-2.
(a) Assuming that the MOSFET is acting as a simple on-off switch, determine the load
power and efficiency.
(b) The MOSFET above is now used in a 20-kHz chopper circuit. Assuming the
parameters remain unchanged, calculate the load power and efficiency at a chopper
duty cycle of 0.4.
