Scr in vehicles
WebbThey can also be used in some electric vehicles. SCRs may be used alone in a circuit to provide one-way current control or wired in reverse-parallel circuits to control AC line current in both directions. See Figure 3. Figure 2. SCRs come in a variety of packages, which increase with an increase in current rating. Figure 3.
