Question

A single phase halfwave rectifier with an ac supply of V1= 47V is used to charge a 12V battery through a 2Ω
resistor(R1) as shown in the picture.
1. draw the voltage waveform across AB;
2. draw the voltage waveform across CD;
3. determine the conduction period of D1;
4. calculate the maximum value of the charging current
through R1;
5. calculate the average value of the charging current
through R1;
6. calculate the PIV across D1.
