Thyristors are a type of semiconductor device that acts as a switch, controlling the flow of electricity in circuits and systems. The most widely used type of thyristor is the Silicon Controlled Rectifier, or SCR. The C180M SCR is a medium to large-sized device that is ideal for a variety of applications. This article provides an overview of the C180M SCR, including its application fields as well as its working principles.

Application Fields

The C180M SCR is an ideal choice for medium to large-scale systems, primarily due to its high surge withstand capability and overload protection. The SCR is often used in a variety of power control applications, as it can handle large load currents and offer low forward drops. It is also a cost-effective choice, as it can cost up to three times less than other thyristors when the same current rating is desired. The C180M can be found in a variety of applications, including motor drives, welding systems, and frequency converters. It is also commonly used in the following industrial applications: large UPS systems, high power UPS systems, large HVAC systems, and elevator power controls.

Working Principles

The C180M SCR is a three-terminal device that comprises a pair of interconnected, reverse-biased PN junction diodes. These diodes control the flow of electrical current through the device, and when an external current or voltage is applied, the diodes become “activated” and the SCR begins to conduct. The current through the SCR continues as long as the voltage remains, as long as the gate current remains above a certain threshold. When the gate current drops below the threshold, the SCR will stop conducting and the current flow will cease. Additionally, the SCR can also be used in phase control applications, in which the on-state current is controlled by a PWM signal.

The C180M SCR has a number of additional features that make it ideal for applications involving power control. These include its soft turn-on and over-current protection, its high surge withstand capability, and its ability to handle large load currents at low forward drops. Additionally, the SCR can also be used in applications requiring high speed operation and great thermal stability.

The C180M SCR is a versatile and cost-effective solution for a wide variety of power control applications. Its high surge withstand capability and overload protection make it suitable for medium to large-scale systems, and its low forward drops and ability to handle large load currents make it an ideal choice for applications requiring power control. Finally, its features such as soft turn-on and over-current protection make it suitable for applications requiring high speed and great thermal stability.
