What is the voltage stress on the switch S1 when it is
off, and what is the voltage stress on the diode D1 when it is off?
Derive the equations based on the input voltage, the output
voltage, and the turns-ratio of the transformer. Draw the
equivalent circuits. Solve for the case when, vIN = 15 V,
N1/N2 = 2, and D = 0.4
