1. 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. -
2. 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.

3. How to improve the efficiency of bridge rectifier?
The use of Schottky diodes in bridge rectifiers can reduce forward voltage drop and improve efficiency. In addition, increasing the filtering capacitor and optimizing the heat dissipation design can also improve the performance and efficiency of the rectifier.

4. How to reduce the ripple voltage of bridge rectifier?
Ripple voltage can be reduced by adding filtering capacitors or using more complex filters (such as inductive filters) in the rectifier circuit, resulting in a smoother DC output.
