POWER CONVERTER USING WIDE BANDGAP SEMICONDUCTOR TECHNOLOGY

摘要

This converter (101) comprises a plurality of cells (130 1, ..., 130 n) identical and connected in parallel, each cell comprising first and second input poles (131 1, ..., 131 N; 1, ..., 132 N) connected to first and second inputs (111, 112) of the converter and first and second output poles (141 1, ..., 141 N; 142 1, .... 142 N) connected to first and second outputs (121, 122) of the converter, each cell comprising: an input capacitor (133) connected between the input poles of the cell; a pair of controlled switches (135, 136) connected in series with each other and having at least one power transistor (153, 151) in wideband semiconductor technology; a very low impedance electrical link between the input capacitor (133) and the pair of controlled switches (135, 136); and an inductor (137) connected to a midpoint (138) between the switches of the pair of controlled switches.
