Abstract
This regulated power supply system with high input voltage dynamics, of the type having a shared inductance buck/boost transformer and having at least two controllable semiconductor switching members, one associated with the buck function of the transformer and the other with the boost function of the transformer, is characterized in that one of the controllable semiconductor switching members is driven by control means as a function of the system's input voltage, and the other is driven continuously by enslavement means on the output voltage.
Claims10
A regulated power supply system with high input voltage dynamics, comprising:
- a shared inductance buck/boost transformer;
- at least two controllable semiconductor switching members, one associated with the buck function of the transformer and the other with the boost function of the transformer,
- wherein the one of the controllable semiconductor switching members is driven continuously using a controller as a function of the system's input voltage, and the other is driven continuously by an enslavement device on the output voltage, and
- wherein the controller and the enslavement device of the controllable semiconductor switching members are active in all operating modes of the regulated power supply system.
