An ideal chopper (buck) operates at a frequency of 500 Hz. It is supplied from a dc source E = 60 V. The load consists of a 3-Ohm and the inductance is 9 mH. Assume the diode is ideal and the battery is lossless. Assume periodic steady state and CCM. Chopper which is Buck which is a step down converter
A) Draw the circuit diagram
B) Derive the expression for the load current, i0(t)
C) For tON/tOFF = 1/1, calculate and draw the current waveform and calculate the mean load voltage and current
D) For tON/tOFF = 4/1, calculate and draw the current waveform and calculate the mean load voltage and current
