Abstract

See full text

This electrical energy converter comprises:

    a first bridge comprising at least a first switching branch between two terminals of an input voltage and including two first switches connected at a first midpoint;a second bridge comprising at least a second switching branch between two terminals of an output voltage and including two second switches connected at a second midpoint;at least one piezoelectric assembly connected between respective first and second midpoints; andat least one switching aid circuit connected to a respective midpoint and configured to, via the flow of a previously received current, discharge a parasitic capacitance of a switch of the bridge to which it is connected, and respectively charge a parasitic capacitance of another switch of said bridge.
