Silicon controlled rectifier power modulator

Abstract

The invention discloses a silicon controlled rectifier power modulator. The silicon controlled rectifier power modulator comprises three-phase electrical interfaces A, B and C, and power and voltage regulating interfaces A1, B1 and C1, wherein the A and the B are connected with an input end of a power and voltage regulator F1, and the A1 is connected with an output end of the power and voltage regulator F1; the A and the C are connected with an input end of a power and voltage regulator F2, and the B1 is connected with an output end of the power and voltage regulator F2; the B and the C are connected with an input end of a power and voltage regulator F3, and the C1 is connected with an output end of the power and voltage regulator F3; the F1, the F2 and the F3 are of the same structure; two input ends of an IC3 are connected with a VIN1 and a VIN2, an output end of the IC3 is connected with a positive power supply interface of an IC1, another output end of the IC3 is connected with one end of an R1, and the other end of the R1 is connected with an inverting input end of the IC1. According to the silicon controlled rectifier power modulator, the F1, the F2 and the F3 form the new three-phase output ends A1, B1 and C1, thus voltage and power between any two of the A1, the B1 and the C1 can be adjusted easily, and the silicon controlled rectifier power modulator can be applied to generator excitation system.

Description

technical field [0001] The invention relates to the field of power generation control, in particular to a thyristor power modulator. Background technique [0002] Thyristor, the abbreviation of silicon controlled rectifier element, is a high-power semiconductor device with a four-layer structure of three PN junctions, also known as a thyristor. With the characteristics of small size, relatively simple structure, and strong functions, it is one of the more commonly used semiconductor devices. The device is widely used in various electronic equipment and electronic products, and is mostly used for controllable rectification, inverter, frequency conversion, voltage regulation, non-contact switch, etc. Dimming lamps, speed-adjusting fans, air conditioners, televisions, refrigerators, washing machines, cameras, combined audio systems, sound and light circuits, timing controllers, toy devices, radio remote controls, cameras and industrial controls in household appliances are wide...
