4. Use a transformer, a bridge rectifier IC, and a capacitor 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 peak-to-peak ripple voltage across the battery should be no more than 2V. Assume the battery internal resistance is 10092. 1) Draw the circuit diagram; 2) Explain how it works; 3) Specify the value of the turns ratio of the transformer and peak inverse voltage of diode. 4) Specify the value of the capacitor for your design, then calculate the peak-to-peak ripple voltage for your designed battery charger. Treat the diode as an offset diode (second approximation) with VBP = 0.65V. 4. Use a transformer, a bridge rectifier IC, and a capacitor to design a battery charger.
