Figure 3. Current wave of the general regulator. 2.1 General reduction voltage regulator principle analysis The craft decides that the silicon stick's voltage regulation range is approximately 10:1. In order to improve the power factor and reduce the harmonics, it usually adopts the viceside multitapped transformer. The circuit diagram of the general viceside multitapped transformer, named multitapped voltage regulator, is shown in Figure 2. There is only one SCR working at one time.At a lower level, SCRs can be used in conjunction with Zener diodes in order to protect circuits from voltage spikes. This is achieved via a circuit known as a "SCR crowbar". The circuit diagram for the SCR crowbar is shown in Figure 3.53. Figure
