Power Electronics combines the solid-state electronic components with control and power systems so as to control the electric power systems, drives, and industrial controls. While modern switchyards and substations heavily rely on power electronics, it is crucial to develop a clear image of the entire subject. WebIO >IH in Figure 3, the TRIAC remains turned on. But if IO falls below IH, the TRIAC will be blocked. It is possible, if the coil is the incorrect type or of poor quality, that the oscillation is insufficiently damped and the TRIAC current falls below the holding current. This results in untimely blocking of the TRIAC.
