Description
Technical Field
The utility model relates to a rectifier technical field specifically is a full wave bridge rectifier.
Background
The rectifier is mainly used for converting alternating current power into direct current power. And full-wave rectification is a circuit that rectifies alternating current. In such a rectifier circuit, current flows through one rectifier device during one half cycle and through the second rectifier device during the other half cycle, and the two rectifier devices are connected such that the current flowing through them flows in the same direction through the load.
In two basic types of rectifiers based on high-power diodes or thyristors, the high-voltage ac power of the grid is converted by means of a rectifier into a dc power supply. Mention will be made of future other types of rectifiers: choppers, chopper dc/dc converters or current source inverter type active rectifiers based on uncontrollable diode leading edge products. Obviously, this state of the art rectifier contains much more development in technology, but it can show advantages, such as that it loads the grid with very little harmonic interference and a power factor of 1.
Full-wave rectification is a circuit that rectifies alternating current. In such a rectifier circuit, current flows through one rectifying device (e.g., a crystal diode) during one half cycle, and current flows through the second rectifying device during the other half cycle, and the two rectifying devices are connected such that the current flowing through them flows in the same direction through the load. The waveform before and after the full-wave rectification is different from that of the half-wave rectification in that two half-waves of alternating current are utilized in the full-wave rectification, which improves the efficiency of the rectifier and facilitates the smoothing of the rectified current. Full-wave rectification is widely used in rectifiers. The power transformer must have a center tap when a full wave rectifier is applied. The direction of current flow through the load resistor R is always the same whether positive or negative half cycles.
Four diodes in a conventional bridge rectifier configuration are the most common way to rectify AC voltage, and operating one diode in a bridge rectifier provides a simple, cost-effective and zero-quiescent current solution for full-bridge rectifiers and automotive alternators, which, although diodes generally have the fastest response speed to negative voltages, result in higher power losses due to positive and negative junction forward voltage drops (Vf 0.7V). These power losses cause heating, requiring designers to perform thermal management, thereby increasing system cost and solution size, and another disadvantage of diodes is high reverse leakage current-up to about 1 mA.
