Power electronic equipment: behind SCR switch

Power electronic device is an important part of power electronic technology and an indispensable part of modern power system. This paper will introduce the basic concept and classification of power electronic devices and the development history of composite power electronic devices.

thyristor

Power electronic devices are important components of silicon controlled switches, including MOSFET, diode, thyristor, IGBT, GTO and IGCT. These devices are divided into voltage control type and current control type according to the switching control mode.

Composite power electronic device

In order to simplify the control and improve the capacity, the voltage control device and the current control device are combined to form a composite power electronic device. Among them, IGBT is the most common and typical compound power electronic device.

Professional literature

If you want to know more about IGBT, you can consult some professional literature. These documents include academic papers, technical reports and patent documents. , can help you understand this kind of composite power electronic device more deeply.
