Method for controlling a full bridge converter with a current-doubler and corresponding digital controller

摘要

A method is described for controlling a Full Bridge converter with a Current-Doubler of the type comprising at least a first and a second half-bridges of diodes connected to respective control transistors. Advantageously according to the invention, the method comprises the steps of:
- detecting a reference value;
- comparing, instant by instant, the reference value with an output voltage value of the converter (1); and
- carrying out a switching from a transfer phase to an energy recirculation phase in correspondence with instants when the output voltage value reaches the reference value. Also a digital controller is described for a Full Bridge converter with a Current-Doubler.
