Connection method of rectifier diode

Rectifier diodes are commonly used components in electronic circuits, mainly used to convert alternating current into direct current. There are many ways to connect rectifier diodes in a circuit, and this article will provide a detailed introduction to several common connection methods.

1. Single phase bridge rectifier circuit

Single phase bridge rectifier circuit is a common rectifier circuit composed of four rectifier diodes and a set of center point grounded loads. Among them, two diodes are connected to one stage of AC power, the other two diodes are connected to the other stage, and the load is connected to the intersection of the four diodes. The voltage of this power supply is the square root of a sine wave, which has strong reliability and stability.

2. Three phase bridge rectifier circuit

A three-phase bridge rectifier circuit is a common high-power rectifier circuit composed of six rectifier diodes and a set of center point grounded loads. Among them, each diode is connected to a stage of a three-phase AC power supply, and the load is connected to the intersection of six diodes. The voltage of this power supply is the square root of the sine wave, which has high efficiency and good stability.

3. Single-phase half wave rectification circuit

A single-phase half wave rectifier circuit is a simple rectifier circuit composed of a rectifier diode and a load. Among them, the rectifier diode is connected to one phase of AC power, and the load is connected to the positive stage of the diode. The power supply voltage is half of a sine wave, with low stability and poor efficiency.

4. Single-phase full wave rectification circuit

A single-phase full wave rectifier circuit is a common rectifier circuit composed of two rectifier diodes and a center grounded load. Among them, one diode is connected to one stage of AC power, the other diode is connected to the other stage, and the load is connected to the intersection of the two diodes. The voltage of the power supply is the square root of the sine wave, which has strong reliability and stability.

5. Connect the rectifier circuit

A series rectifier circuit is a special rectifier circuit composed of two or more rectifier diodes connected in series. Among them, the positive stage of each diode is connected to the negative stage of the previous diode, and the load is connected to both sides of the entire power supply. The voltage of this power supply is the square root of a sine wave, with high efficiency and good stability.
