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 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.
