三端双向可控硅（Triac）是一种高速固态器件，可以在正弦波形的两个方向上切换和控制交流电源。 本文引用地址： 晶闸管和三端双向可控硅都可以用于控制灯具、电机或加热器等。然而，使用晶闸管控制此类电路的一个问题是，像二极管一样，晶闸管是一种 ...

Several different technologies and designs are available among solid-state switches today. The major families are the standard Triacs (triode for alternating current), the snubberless Triacs, and the ...

Triacs are bidirectional ac switches that can control loads with currents as high as 25A rms at voltages as high as 600V. They find wide use in motor-speed, heater, and incandescent-lamp controls.

Triacs are used to control ac mains loads in home appliances, and commercial and industrial equipment. In the majority of applications, the triac will dissipate sufficient power to make thermal ...

STMicroelectronics’ 800V 8H triacs operate at full rated current up to the maximum junction temperature of 150°C, allowing heatsinks in drives for AC loads to smaller, claims the company. The family ...

To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...
