Education 7.10 Field-effect-controlled Thyristors adminJan 28, 2020 Two relatively recent technologies designed to reduce the “driving” (gate trigger current) requirements of classic...
Education 7.9 The Silicon-Controlled Switch (SCS) adminJan 28, 2020 If we take the equivalent circuit of an SCR and add another external terminal, connected to the base of the top...
Education 7.8 The Unijunction Transistor (UJT) adminJan 28, 2020 Unijunction transistor: Although a unijunction transistor is not a thyristor, this device can trigger larger thyristors...
Education 7.7 Optothyristors adminJan 28, 2020 Like bipolar transistors, SCRs and TRIACs are also manufactured as light-sensitive devices, the action of impinging...
Education 7.6 The TRIAC adminJan 28, 2020 SCRs are unidirectional (one-way) current devices, making them useful for controlling DC only. If two SCRs are joined...
Education 7.5 The Silicon-Controlled Rectifier (SCR) adminJan 28, 2020 Shockley Diodes and Silicon Controlled Rectifiers (SCRs) Shockley diodes are curious devices, but rather limited in...
Education 7.4 The DIAC adminJan 28, 2020 Like all diodes, Shockley diodes are unidirectional devices; that is, these only conduct current in one direction. If...
Education 7.3 The Shockley Diode adminJan 28, 2020 Our exploration of thyristors begins with a device called the four-layer diode, also known as a PNPN diode, or a...
Education 7.2 Gas Discharge Tubes adminJan 28, 2020 If you’ve ever witnessed a lightning storm, you’ve seen electrical hysteresis in action (and probably didn’t...
