Converter of one direct current to another direct current with control signal interleaving, and power supply system including such a converter

摘要

The converter (20) has modules (70) forming an H-bridge, where each module comprises a switching branch (72) comprising controllable electronic switches (74) connected in series between terminals (40). The controllable electronic switches are connected with each other at middle point (76). A controlling unit (80) controls the modules based on commutative law, where the law of the each module has same frequency and is phase shifted with respect to each other. An independent claim is also included for a power supply system for load comprising a control unit.
