ABSTRACT:
A device for regulating the intensity of an electric current in a receiver has a primary circuit containing a rectifier bridge connected across the terminals of a main power supply, thus defining a positive terminal and a negative terminal on the bridge after rectification. The positive and negative terminals are connected in series to a high-speed on/off switch and a parallel resonant circuit. The parallel resonant circuit includes an inductor and a capacitor connected in parallel. The device also includes a secondary circuit coupled magnetically to the primary circuit. The secondary circuit is connected in series with the receiver whose intensity it is desired to regulate.
