Converter having a plurality of channels

Abstract

A converter having a plurality of channels comprises a transformer having a primary winding and at least one secondary winding. First switch means connected to the primary winding serve to chop a substantially DC voltage in compliance with a first squarewave periodic signal in order to form an input signal, the input signal presenting a positive sequence phase and a freewheel phase. Second switch means at the input of one of the channels serves to chop an output signal at the secondary winding corresponding to said channel in compliance with a second squarewave periodic signal. The converter also comprises measurement means for measuring a primary current and connected to the primary winding. According to the invention, the converter further comprises storage means for storing a plurality of measured values corresponding to the primary current, the values being measured at distinct times during the positive sequence phase of the input signal, and also means for processing the measured values.
