3. Use a transformer with the turns ratio of 5:1, two diodes, and a resistor to design a battery charger. If the input power is from the regular power line (120rms, 60Hz) and the battery is 12-V battery. The maximum charging peak current and maximum charging peak voltage of the battery are 0.5A and 15V, respectively. 1) Draw the circuit diagram; 2) Explain how it works; 3) Specify the value of the limiting current resistor and reverse breakdown voltage of diode. Treat the diode as an offset diode (second approximation) with Vpp = 0.7V. 3. Use a transformer with the turns ratio of 5:1, two diodes, and a resistor to design a battery charger.
