ABSTRACT:
A cut-off amplifier regulating the supply voltage of a load. This cut off amplifier comprises n bidirectional switches receiving input voltages which are alternatively positive and negative. These switches are connected to the load through a choke and to control means which place only one of the switches in the "on" state when the others are in the "off" state. The phase of the input voltage which is off (selected by the switches) depends on the comparison between the voltage applied to the load and a reference voltage.
