The Single-phase contact type variac voltage regulator circuit is as shown in the figure: When the capacity of each variac is not enough, you can connect several variacs in parallel. In order to guarantee the equation of the secondary side voltages when it is operating and avoid to cause the potential difference, the adjustment of the parallel transformers must be synchronized. In addition, it needs an output port series reactor to evenly distribute the power.
