You are tasked to design a dc power supply that operates from a single-phase ac supply (50Hz) with source inductance
of 1.5mH/phase. It is required to supply a dc load (resistive) with 55A at 322 Volt. Assume infinite inductive filtering and
the use of power diodes with a forward voltdrop of 0.7V. Consider the bridge converter topology and specify the following
design parameters,
30) the loss in voltage due to commutation overlap;
31) the r.m.s. ac supply voltage required;
32) the overlap angle;
33) the transformer utilisation factor;
34) the rectification efficiency of the converter;
35) the dc current rating of the rectifier diodes;
36) the r.m.s. current rating of the rectifier diodes;
37) the form factor of the diode current;
38) the peak repetitive forward current rating of the rectifier diodes;
39) the peak repetitive reverse voltage rating of the rectifier diodes.
