Electrical Engineering

Consider an ideal down converter supplying load resistance of 80ohms from a voltage source rated 9V and 250mA. The converteroperates at 70-kHz and is designed for 5% voltage ripple and 10%current ripple with a duty time of 60%.

a) Calculate the output voltage, output voltage ripple, outputcurrent and output current ripple.

b) Calculate the cycle period, T on and T off.

c) Calculate the required inductance and capacitance values

d) Calculate the output voltage as functions of time

e) Graph the ideal output voltage and inductor currentwaveforms.
