1. What is the working principle of bridge rectifier?

The bridge rectifier converts the input AC power into DC power through an arrangement of four diodes. Every half cycle, two diodes conduct, converting both positive and negative half waves of alternating current into direct current in the same direction.
2. What are the common applications of bridge rectifiers?

Bridge rectifiers are widely used in power supplies, chargers, household appliances, power tools, lighting systems, and various electronic devices to provide stable DC power.
3. What is the peak reverse voltage (PIV) of a bridge rectifier?

Peak reverse voltage (PIV) is the maximum voltage that a bridge rectifier can withstand when reverse biased. When selecting a bridge rectifier, the PIV should be at least twice the peak voltage of the input AC power to prevent diode breakdown under reverse voltage.
4. Can bridge rectifiers be used for high-frequency applications?

Traditional silicon bridge rectifiers have low efficiency in high-frequency applications and are prone to significant power losses. However, bridge rectifiers using Schottky diodes or fast recovery diodes can significantly improve high-frequency rectification performance.
