Electrical Characteristics For Bridge Rectifiers W005G Thru W10G

Product Introduction

A diode rectifier bridge is an electrical device that converts (“rectifies”) alternating current into pulsating (direct current) electricity. The rectification using a diode bridge is called full wave

There are single-phase bridges and multi-phase bridges. The single-phase bridge is made based on the Graetz bridge circuit. At first, it used vacuum diodes, which were considered a complex and expensive solution; On the contrary, Mitkevich circuits are commonly used, where the secondary winding of the transformer has an intermediate terminal. Nowadays, semiconductor diodes have become cheaper and almost everyone can use them. In most cases, bridge circuits are used, and except for the Mitkevich circuit used in some low-voltage rectifiers, they have higher efficiency under the same conditions.

Any type of rectifier valve can be used instead of diodes in the circuit, such as selenium rectifiers, mercury valves, etc., and the working principle of the circuit will not change.

In addition, controlled valves such as thyristors or ignition tubes are used in the bridge arm, and the phase pulse control of the controlled valve can be used to control the output voltage of the rectifier

Advantages of rectifier bridge:

The full wave rectification using a bridge (compared to half wave rectification) has the following advantages:

At the output of the bridge, the voltage has an increased ripple frequency, which simplifies the ripple filter;

In the secondary winding of the transformer that supplies power to the bridge, there is no direct bias current, which is beneficial for the operation of the transformer and reduces its required size;

Improved the overall power utilization of the transformer (approximately 0.45 for a half wave rectifier, as only half a cycle of AC current flows through the load), allowing for a smaller magnetic core size.
