1. A full-wave single-phase passive rectifier is given below: The input AC voltage is 120 V at 60 Hz. (a) Find the average dc-link voltage when there is no filter capacitor. (b) Calculate the maximum dc-link voltage that this passive rectifier can reach. (c) What would be the minimum diode voltage rating that can safely operate this rectifier assuming the dc-link voltage is at its peak (estimated from (b))? 2. A full-wave three-phase passive rectifier is given below: The input AC voltage is 240 V (line-to-line) at 60 Hz. (a) Find the average dc-link voltage when there is no filter capacitor. (b) Calculate the maximum dc-link voltage that this passive rectifier can reach. (c) What would be the minimum diode voltage rating that can safely operate this rectifier assuming the dc-link voltage is at its peak (estimated from (b))? (d) Assuming the phase AB, BC, and CA line-to-line voltage waveforms are given below: During the period from 30 to 90 degree, which diodes from the rectifier circuit will turn on? Which diodes will turn on during 270 to 330 degree? 3. A three-phase inverter is given below: The input DC voltage is 400 VDC. (a) What is the maximum line-to-line voltage and rms line-to-line voltage? (b) What is the maximum line-to-neutral voltage (phase voltage) and rms phase voltage of this inverter?
