Abstract
A voltage control regulator features a power switch in the form of a transistor that is normally actuated for a constant switch-on time interval during each variable period interval (T). The type of control required in this case comprises, conventionally, a monostable multivibrator, a controller, and a voltage/frequency converter. The present control system is subordinated to an emergency control circuit which, via a priority loop, intervenes in the control process as soon as the current flowing through the switching transistor threatens to become excessive. This emergency control unit thus constitutes a predictive type of control that employs knowledge of the operation of the voltage control regulator and the instantaneous values of the input and output voltages of the voltage control regulator, in order to predict the voltage increase during the period interval (T). Such an arrangement permits the emergency control unit to react very quickly.
