Abstract
A power converter including: a first branch and a second branch of at least two series-connected switches each, coupled in parallel between a first terminal and a second terminal and having the junction points of their switches coupled to two terminals of application of a first voltage; a third branch and a fourth branch of at least two series-connected switches each, coupled in parallel between a third terminal and a fourth terminal, and having the junction points of their switches coupled to two terminals for supplying a second voltage; and at least one piezoelectric element coupling the first terminal to the third terminal.
Claims11
A power converter comprising:
- a first branch and a second branch of at least two series-connected switches, each switch in the at least two series-connected switches coupled in parallel between a first terminal and a second terminal and having junction points of each switch in the at least two series-connected switches coupled to a first set of two terminals of application of a first voltage;
- a third branch and a fourth branch of the at least two series-connected switches each switch in the at least two series-connected switches coupled in parallel between a third terminal and a fourth terminal, and having junction points of each switch in the at least two series-connected switches coupled to a second set of two terminals for supplying a second voltage;
- and
- at least one first piezoelectric element coupling the first terminal to the third terminal,
- wherein turning on of each switch in the at least two series-connected switches is performed under an approximately zero voltage thereacross, control of each switch in the at least two series-connected switches being synchronized with respect to a current internal to the piezoelectric element.
