Abstract
The present invention relates to a system for the conversion of DC electric power into three-phase electric power comprising three commutation arms (A, B, C), a modulation circuit, an electrical energy recovery module (8) and filtering means (7). The filtering means (7) comprise a capacitor (Cf) and an assembly formed from a filtering coil (Lf) connected in series with a diode (D).
Claims23
A system for the conversion of DC electrical power into three-phase AC electrical power comprising three commutation arms, a modulation circuit for reducing switching loss and overshoot of voltage and current comprising one capacitor per AC output phase of the system and a coil, and an electrical energy recovery module connected to the commutation arms and to the modulation circuit, wherein the conversion system comprises a filtering circuit for each output phase of the system including a capacitor and an assembly formed from a filtering coil connected in series with a diode.
