Under normal conditions, the output voltage is 1.2 * 20 = 24 V. When a diode is open, the output voltage is 0.6 * 20 = 12 v. if the measured output voltage of the circuit is the following values, it indicates that the possible faults of the circuit are: & nbsp; & nbsp; (1) capacitor damage or loss of capacity; (2) load open circuit; (2) & nbsp
