High Current Rectifier - Global Industry Market Analysis Report 2020-2031

A high-current rectifier is an electrical device that converts alternating current into direct current, and plays a key role in application scenarios that require a large amount of direct current energy. Its core function is to use the unidirectional conductivity of semiconductor devices to convert periodically changing alternating current into direct current with constant direction to meet the needs of various types of direct current electrical equipment.

Its working principle is based on the unidirectional conduction characteristics of the diode. In the positive half cycle of the alternating voltage, the diode is turned on, and the current flows to the load through the diode; in the negative half cycle of the alternating voltage, the diode is cut off, and the current cannot pass, thereby realizing the conversion of alternating current to direct current. For high-current rectifiers, in order to meet the processing requirements of large currents, multiple diodes are usually used to form a rectifier bridge. Common ones are single-phase bridge rectifier circuits and three-phase bridge rectifier circuits. In the three-phase bridge rectifier circuit, six diodes cooperate with each other, so that at least two diodes are turned on at any time of the AC power supply, ensuring the continuous output of current, and can effectively improve the rectification efficiency and the stability of the output current.

The high-current rectifier is mainly composed of rectifier diodes, heat sinks, filter circuits, and control systems. Rectifier diodes are key components for current conversion. They need to have high withstand voltage, high current handling capacity, and low on-resistance to reduce energy loss and heat generation. Since a large amount of heat is generated when a large current passes through, a heat sink is essential. It can dissipate the heat generated by the diode in time to ensure the normal operation of the equipment. The filter circuit is used to smooth the rectified DC output, reduce the fluctuation of voltage and current, and make the output DC more stable. Common filtering methods include capacitor filtering, inductor filtering, and LC filtering. The control system is responsible for monitoring and adjusting the working state of the rectifier to ensure that it can operate stably under different load and input voltage conditions, and realize overcurrent protection, overvoltage protection, and temperature protection.

Depending on the semiconductor devices used, high current rectifiers are mainly divided into silicon rectifiers and thyristor rectifiers. Silicon rectifiers use ordinary silicon diodes, which have the advantages of simple structure, high reliability, and low cost. They are suitable for occasions that are cost-sensitive and have low control requirements, such as general DC power supply. Thyristor rectifiers use thyristors as rectifying elements. Thyristors have the characteristics of strong controllability. By controlling the trigger angle of the thyristor, the output DC voltage can be flexibly adjusted. It is widely used in fields that require precise control of DC voltage and current, such as motor speed regulation, electroplating power supply, etc.

High-current rectifiers are widely used in many fields. In the power industry, they are used in high-voltage DC transmission systems to realize the mutual conversion of AC and DC, and improve the efficiency and stability of power transmission; in the metallurgical industry, they provide high-current DC power for electrolytic processes such as electrolytic aluminum and electrolytic copper to ensure the smooth progress of the metal smelting process; in the electroplating industry, they provide stable DC current to ensure the uniformity and quality of the electroplating layer; in electric vehicle charging facilities, AC is converted into DC to charge electric vehicle batteries.

With the continuous development of power electronics technology, high-current rectifiers are also developing in the direction of high efficiency, intelligence, and miniaturization. In the future, new semiconductor materials such as silicon carbide (SiC) and gallium nitride (GaN) will gradually be used in high-current rectifiers. These materials have higher electron mobility, breakdown electric field strength and thermal conductivity, which can significantly improve the efficiency and power density of rectifiers and reduce energy loss and equipment size. At the same time, the application of intelligent control technology will enable rectifiers to automatically adjust their working state according to load requirements, achieving more precise control and higher reliability. In addition, in order to meet environmental protection requirements, high-current rectifiers will also develop in the direction of low harmonics and low electromagnetic interference to reduce the impact on the power grid and surrounding electronic equipment.
