VHFD37-14IO1 Application Field and Working Principle

VHFD37-14IO1 is a type of thyristor module designed and developed by the leading manufacturer of power semiconductors, IXYSCorporation. It is designed to be used in various application fields, ranging from medical to industrial, and is capable of controlling power used in various industrial and telecommunications systems.

Introduction to Thyristors

A thyristor is a type of semiconductor switch, typically made from silicon, germanium, and zirconium silicate. Thyristors can be used to regulate the flow of electric current for purposes such as overvoltage protection, voltage limitation, and even the control of power in electrical devices.

Thyristors are built from three layers of semiconductor material, wherein one of these layers is composed of a material that acts as a gate. When two devices with different potentials are connected, current and voltage can be controlled by the gate.

Typical applications of thyristors are in the fields of power electronics, communications, medical electronics, and environmental engineering. Certain types of thyristors allow for a high amount of power to be controlled, while other can extend the lifetime of a device by providing overvoltage protection.

Introduction to SCR’s

Thyristors are made up of two types of devices: silicon control rectifiers (SCR) and thyristors. The Silicon Controlled Rectifier (SCR) is designed to control the flow of electric current in both directions by controlling the electric gate. Hence, an SCR is a three-pin device, with the electric gate connected to the anode and the cathode connected to the other two pins.

SCR’s are primarily used to switch power from one device to another. They are also used for voltage regulation, and as a switch in devices that require a high current, such as UPS systems, DC motors and AC inverters.

Introduction to Modules

Thyristor and SCR modules are designed to control the power delivered to different electrical devices. Among other things, they are used to regulate and activate various components in power systems, such as alternators, and to protect the system against short circuits.

Generally speaking, modules have advantages over discrete components, such as higher thermal efficiency, decreased losses, improved current and voltage regulation, and a better control over parameters such as switching time and delay.
