A DC battery is charged through a resistor R as shown in Fig. Derive an expression for the average value of the charging current in terms of Vm, E, R, etc., assuming that the SCR is fired continuously.(a) For an AC source voltage of 480 V, 50 Hz, find the value of the average charging current for R = 20 Ω and E = 200 V. (b) Find the power supplied to the battery and the power dissipated in the resistor. (c) Calculate the supply power factor.

A single-phase full-bridge diode rectifier is supplied from a 120 V, 50 Hz source. The load consists of R=20Ω and a large inductance to maintain a constant load current. Determine:(a) The average values of output voltage and output current, (b) The average and RMS values of diode currents, (c) The RMS values of output and input currents, and the supply power factor.
