RC Combined voltage starting circuit

Posted on Mar 28, 2007

Circuit shown in Figure 3-35. The advantage of this approach is to start the motor running from start to full voltage step-down switching over process uninterruptible power sup

ply, thus avoiding the process of switching currents caused by a sudden change in the induced voltage of the motor insulation damage. In addition, this method can greatly reduce the series resistor (generally can be reduced about 80 jumping), so when you start startup resistor energy consumption will also be reduced by about 80%.
