Buck chopper in power electronics
Webpower converters is difficult and expensive. The ideal dc-dc converter exhibits 100% efficiency; in practice, efficiencies of 70% to 95% are typically obtained. This is achieved using switched-mode, or chopper, circuits whose elements dissipate negligible power. Pulse-width modulation (PWM) allows control and regulation of the total output voltage. WebI had a quiz on power electronics and the following questions were asked: Question 1: Consider the buck chopper in Figure 1, operating at 100 kHz frequency, with the switch duty ratio of 0.5 and input voltage of 100 V(DC). The load is resistive with R = 10 ohms, put across the filter capacitor.
