WebConsider the step-down (buck) chopper circuit shown in the figure below and assume the switch and diode to be ideal. Assume switching frequency, f= 10 KHz, duty cycle D=0.5, … Web6.2.1 Working principle of buck–boost converter. The working principle of the DC-to-DC converter is that the inductor in the input resistance has the unexpected variation in the input current. If the switch is on, then the inductor feeds the energy from the input and it stores the energy of magnetic energy.
