The Application of Power Electronic Switches in High Voltage Quick Switching Device

Microcomputer auxiliary power switching device turn-on time is generally 70ms ∼ 80ms, when some loads are sensitive and require short switching time that a few milliseconds or less, the microcomputer auxiliary power switching devices can not meet the requirements, which requires faster switching devices. Power electronic switch is a fast open-off switch device to meet the sensitive load requirements on switching time. This article mainly introduced the application of power electronic switch as high voltage quick switching device, and analyzed harmonic problems of power electronic switch.
