1. What is the working principle of a single rectifier diode?
A rectifier diode conducts current when forward biased, converting the positive half wave of alternating current into direct current. When reverse biased, the diode blocks the current, thereby preventing the negative half wave from passing through and achieving rectification effect.
-
2. What is the maximum reverse voltage (PIV) of a rectifier diode?
The Peak Inverse Voltage (PIV) is the maximum reverse voltage that a diode can withstand. When selecting a diode, the PIV must be higher than the maximum reverse voltage in the circuit, usually twice or more the input voltage.
-
3. How to determine if the rectifier diode is damaged?
Use a multimeter to measure the forward and reverse resistance of a diode. If the diode exhibits low impedance or high impedance in both directions, it may have been damaged. Under normal circumstances, there should be low impedance when conducting in the forward direction, and high impedance when conducting in the reverse direction.

4. How to improve the efficiency of rectifier diodes?
The use of Schottky diodes or fast recovery diodes can reduce forward voltage drop and reverse recovery time, thereby improving the efficiency of rectifier circuits, especially in high-frequency applications.
