1. It is required to design a 300 V, 10 a full-wave, d.c converter for supplying a resistive load. The available a.c source is a single phase 220 V power supply. a) What are the possible connections? b) For each connection sketch the a.c supply voltage and current, the output d.c voltage and current, the diode currents, and the reverse voltage on any diode. c) Are you going to use a transformer or not? d) If “Yes”: determine the transformer turns ratio. If “No”: explain why? e) Calculate the transformer utilization factor and the ripple factor for each case. f) Which configuration you prefer and why? g) If one of the diodes in your selected circuit was damaged and acted as an open circuit, sketch the output voltage waveform and comment on your results?
