SpletWhen switching inductive loads with a DC relay such as relay sequence circuits, DC motors, DC clutches, and DC solenoids, it is always important to absorb surges (e.g. with a diode) … SpletFor inductive loads, an RC snubber circuit, as shown in Figure AN1007.1, is required. However, a snubber circuit is not required when an alternistor Triac is used. Figure AN1007.2 illustrates an analysis to better understand a typical static switch circuit. The circuit operation occurs when switch S 1 is closed, since the Triac Q 1 will initially
