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 advantages of bridge rectifier compared to single diode rectifier?
Bridge rectifier is more efficient than single diode (half wave) rectifier because it can use two and a half cycles of AC power, not just one and a half cycles, thereby improving the output power efficiency and stability.
-
3. How to choose a suitable bridge rectifier?
When choosing a bridge rectifier, the following factors need to be considered:
Current capacity: Select the appropriate rectification current capacity according to the load demand.
Voltage level: Ensure that the rectifier can withstand the maximum peak voltage of the input.
Forward voltage drop: The lower the forward voltage drop, the higher the efficiency.
Packaging form: Choose the packaging type that is suitable for the circuit board or heat dissipation requirements. -
4. 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.
