Thyristors - SCRs - Modules

Thyristors are a type of device used to control electric current in an electronic circuit, commonly known as a semiconductor. They are commonly used as electronic switches in applications such as power transmission, relays, medical equipment, and AC/DC power control circuits. SCRs, or Silicon Controlled Rectifiers, are a type of thyristor specifically designed to control and limit the amount of current that can flow through an electronic circuit. These are typically used in applications such as AC/DC power regulation, motor speed and torque control, and voltage regulation.

MSTC25-08 Application Field and Working Principle

MSTC25-08 is a type of SCR module designed for digital control of AC/DC power conversion from a 12V to 600V output. It consists of eight thyristors integrated on a single substrate and controlled by a separate control board. The main application for these modules is in the regulated AC/DC power supplies used in all types of power electronics, ranging from consumer audio devices, motor controllers, and various industrial and domestic appliances. The devices have inherent protection against current spikes and transient over-currents, making it an ideal choice for use in power electronics.

The principle of operation of MSTC25-08 modules is based on the use of thyristors to control electric current using gate signals. The gate signal is a square-wave current pulse that is applied to the gate of each thyristor. When the gate signal is applied, the thyristor is turned on and begins to conduct current through the load, while in the absence of the gate signal the current will be cut off. This allows for fast switching of current without the need for additional mechanical switches, resulting in improved power efficiency and reliability.

In operation, the MSTC25-08 module controls the AC/DC power conversion process by applying a variable gate signal that is in-phase with and proportional to the AC voltage waveform from the input voltage source. This is done by turning on and off the thyristors in a sequential, timed sequence which is determined by the control board. This allows for precise regulation of the output voltage, which is necessary in power electronics applications. The module is also protected from over-current by a thermal cut-off feature which will automatically shut off the supply if the current rating is exceeded.

The MSTC25-08 module is a reliable, cost-effective solution that is suitable for use in a variety of power electronics applications. It offers an integrated solution with a single substrate and separate board for control, making it easy to install and use. The module is highly-reliable and is protected against current spikes and transient over-currents, making it a great choice for AC/DC power regulation.
