A buck converter connected to a 100-V battery pack supplies an RL load, where R = 0.5 ? and L = 1 mH. The thryristor switch is on for 1ms, and the period of the switching waveform is 3ms. Calculate the average value of the load voltage and the power supplied by the battery.
Find:
Average values of current and voltage; power drawn from battery supply.
Analysis:
From the data given, ? = 1ms/3ms = 0.333. Since the period of the waveform is 3 ms, we can calculate the switching frequency to be:
