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 difference between a single rectifier diode and a bridge rectifier?
A single rectifier diode can only rectify the positive half wave of AC power (half wave rectification), while a bridge rectifier composed of four diodes can rectify the positive and negative half waves of AC power (full wave rectification), with higher efficiency and smoother output.

3. What is a fast recovery diode?
Fast recovery diode is a special type of rectifier diode with a short reverse recovery time, suitable for high-frequency power supplies and switch mode power supplies (SMPS) applications, reducing switching losses.
-
4. What is the reverse recovery time of a rectifier diode?
Reverse recovery time refers to the time required for a diode to transition from a forward conducting state to a reverse blocking state. A shorter reverse recovery time is particularly important in high-frequency applications to reduce power loss.
