What is the working principle of the power regulator thyristor regulator


The power regulator thyristor regulator is the abbreviation of thyristor rectifier element. It is a four-layer structure high-power semiconductor device with three PN junctions, also known as thyristor. It has the characteristics of small size, relatively simple structure and strong functions, and is one of the more commonly used semiconductor devices. It is the perfect combination of thyristor AC switch technology and transformer technology. Using high-power thyristor thyristor regulator to replace mechanical and carbon brushes to control voltage regulation, the capacity can be 2000kVA, the compensation range can reach up to ± 50%, and the efficiency can reach more than 99%, which is leading the development of high-power power regulators The advanced products in the direction are energy-saving and environmentally friendly products, with all protection functions, very reliable and adaptable. Realizes all-contactless voltage regulation, has the advantages of good stability and high efficiency, has no pollution to the power grid, can reliably work continuously under various harsh power grids and complex loads, has a very long service life, and can continue to be fault-free It has been operated for more than 100,000 hours, realizing long-term maintenance-free of the regulator.

The replacement circuit of the thyristor regulator due to the immaturity of the DISC semiconductor structure in the early days, the discharge voltage of the thyristor regulator is determined by the voltage division of DB3, the life is longer, but the current energy is smaller, and the switching speed is slower. It is more suitable for high-pressure sodium lamps and less suitable for occasions where metal halide lamps require pulse width. The structure can be improved but the cost is higher.

The power regulator adjusts the level of the rectified voltage to control the feeding amount of the electromagnetic vibration feeder. The feeder uses thyristor regulator to rectify the power supply, change the conduction angle of the thyristor regulator, you can control the output voltage level, according to the conditions of use, you can take different signals to control the size of the thyristor regulator conduction angle In order to achieve the purpose of automatic quantitative feeding, the accurate control of the feeding of the electromagnetic vibrating feeder directly affects the efficiency and quality of production. It can control the electromagnetic vibrating feeder to uniformly feed, with simple structure, easy adjustment, stable operation and long distance Microcomputer control and other features can realize centralized control and automatic control of the production process.
