5. A single-phase diode bridge rectifier is supplying a load of 100 2. A capacitor needs to be connected across the load to limit the pcak-to-peak voltage ripple to 10V. The AC supply voltage is 230V RMS, 50 Hz. (a) What is the value of capacitance needed? Make suitable assumptions to simplify the calculation and state the same. (b) How long does cach diode in the rectifier conduct in one line cycle? (calculate the approximate time in milli-seconds) (c) Determine the peak value of input AC current. (d) Sketch the waveforms of output DC voltage and input AC current.

Note:
1. Answer all the questions.
2. Mention relevant units to cach quantity wherever applicable, for example 3V, 2A.
3. Sketch the waveforms in periodic steady-state unless otherwise specified; Mark all the sig-
nificant r and y values while sketching a waveform/function y(r).
4. Values of the AC voltages and currents indicated are usually RMS values, unless otherwise
specified.
5. The term line voltage' usually refers to the line-to-linc voltage and 'phase voltage' refers
to the line-to-neutral voltage in a 3-phase/polyphase system.
6. The voltage indicated for a 3-phase/polyphsae AC supply is usually the line voltage, unless
otherwise specified.
