ABSTRACT:
In electrical circuit means having a load, an SCR pulse controller in series with the load and including a commutation capacitor, a transmission line connected to the load and pulse controller to supply the load from a D.C. source, and, a reservoir capacitor shunting the transmission line, the provision of control means which during interpulse periods of the controller by repeatedly discharging the reservoir capacitor limit the voltage to which the reservoir capacitor charges above the voltage of the source.
