Scr based rectifier
WebTo design the controlled feature, The silicon-controlled rectifier (SCR) is basically a thyristor, a four-layer (P–N–P–N) semiconductor device that contains three PN junctions in series called a Shockley diode. If a voltage higher than the trigger voltage is not applied to that voltage, the shackle diode is closed with too much resistance. WebThe SCRs are used for home appliance control include lighting, temperature control, fan speed regulation, heating, and alarm activation. For industrial applications, SCRs are used …
