Thyristor is also called silicon controlled rectifier (SCR), the following is described as SCR (1) Working conditions of SCR. Because SCR has only two working states of on and off, it has switching characteristics. This characteristic requires certain conditions to be transformed. Such conditions are shown in Table 1. ① When the SCR bears the…
There are two main types of switching devices used in modern UPS, namely Thyristor (SCR) and IGBT. SCR is mainly used in multi-phase phase-controlled rectifiers and bypass switches. Let’s talk about the Thyristor (SCR) Thyristor (SCR), also called silicon controlled rectifier, is the earliest semi-controlled switching device used in power electronics. It is a four-layer…
