Power regulator is a type of power control device based on thyristor (thyristor) and with intelligent digital control circuit as the core, abbreviated as power regulator. Power regulators have many advantages such as high efficiency, no mechanical noise and wear, fast response speed, small size, and light weight. Next, let's introduce the thyristor of the power regulator. The full name of thyristor is thyristor (also known as thyristor, abbreviated as SCR), which is a power semiconductor device. It has many advantages such as large capacity, high efficiency, good controllability, long lifespan, and small size, and is a bridge between weak current control and controlled strong current. From the perspective of energy conservation, power electronics technology is hailed as a new electrical technology. The energy utilization rate in our country is relatively low. Calculated based on the energy consumption per unit of national production, China's energy consumption is 4.98 times that of France and 4.43 times that of Japan. Therefore, the widespread use of electrical control devices with thyristors (thyristors) as the core is an important measure for China to effectively save electricity.

Thyristors (thyristors) are mainly used in the fields of AC voltage regulation, controllable rectification, and contactless power static switches in China's industrial, agricultural, and civilian production. AC voltage regulation is the use of the switching characteristics of thyristors (thyristors) to replace old-fashioned contact voltage regulators, inductive voltage regulators, and reactor voltage regulation. The transformation from AC to variable AC using thyristors (thyristors) is called AC voltage regulation.

It is mainly used in temperature control, lighting control, and AC motor voltage regulation speed and other fields. Controllable rectification is a rectifier composed of thyristors (thyristors) that can conveniently change the magnitude of the DC output voltage to control rectification while keeping the AC voltage constant. Thyristor controlled silicon rectifier has replaced DC generator sets for DC drive speed control devices, and is widely used in fields such as steel rolling, electrolysis, electroplating, machine tools, papermaking, textiles, and excitation.
