The dc converter in the next figure has a resistive load,
R = 15 and input voltage, Vs = 240 V. When the converter
remains on, its voltage drop is Vch = 1.75 V and chopping)
frequency is f = 15 kHz. If the duty cycle is 90%, determine
(a) the average output voltage Va,
(b) the rms output voltage Vo,
€ the converter efficiency,
(d) the effective input resistance Ri, and
€ the rms value of the fundamental component of harmonics
on the output voltage.
