4.
In a Full-bridge converter shown in Fig. 8-9, V=30V, f, = 200 kHz, and
NIN₂ =4. The output voltage is regulated by PWM such that V=5V. The
output power P = 250W and the peak-peak ripple in the output inductor
current is 10 percent of its average value at full-load. Calculate the value
of the filter-inductor L. Calculate and plot all the waveforms associated with
this converter. Assume the transformer ideal and the flux waveform to be
symmetric with the same positive and negative peak amplitudes.
