SCR test of circuit

Circuito de teste de SCR

SCR é a sigla de Silicon-controlled Rectifier ou semiconductor-controlled rectifier, in Portuguese silicon rectifier controller. SCR is a semiconductor four-layer solid state device used as control. SCRs are unidirectional devices (in other words, can conduct current in only one direction), in opposition to the TRIAC is bidirectional (in other words, current can flow through it in any direction). SCRs can ...
