Consider the half-wave rectifier shown below. It needs to deliver 0.1 A and an average of 15 V to a load. The source is 60 Hz and the diode has a 0.7 V drop. The allowable ripple is no more than 0.4 V (2.5%). Find: Peak AC voltage Vm of the source a) b) The minimum value of the smoothing capacitor(s) c) Comment on the type of capacitor and its/their values you would use for this amount of capacitance vs(t) K Load UL

Determine which diodes are forward-biased and which are reverse-biased in the configurations.. Assuming a 0.7-V drop across each forward-biased diode, determine the output voltage.

The four diodes used in a bridge rectifier circuit have forward resistances which may be considered constant at 1 ohm and infinite reverse resistance. The alternating supply voltage is 220 V r.m.s. and load resistance is 580 ohm. Calculate (i) mean load current and (ii) power dissipated in each diode.
