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 dio
