The converter of a direct current by a direct current with interlocking of the control signals, and power supply system comprising such a converter

摘要

The converter (20) of a direct current by a direct current comprises: - the first two terminals (40), two second terminals (v +, -), - two modules (70) forming an h bridge, each module being connected between the first two terminals (40) on the one hand, and a second terminal (v +, -), respectively, on the other hand, each module (70) comprising at least one switching branch (72), each switching branch (72) comprising at least two electronic switches are controlled (74) connected in series between the first terminals (40) and connected together by a junction point (76) connected to the second terminal (v +, -), - of the means (80) of the control of the electronic switches (74) of the modules, each according to a law of switching. The laws of switching of each of the modules (70) are of the same frequency and are phase shifted from one another.
