專利摘要

A method is for controlling a three-phase current converter. First, subtract a second reference current signal representing the predicted current of the three-phase terminals in the present switching cycle from a first reference current signal representing the predicted current of the three-phase terminals in the next switching cycle to obtain a predicted variation. Then, subtract a feedback current signal representing the feedback current of the three-phase terminals in the previous switching cycle from the second reference current signal error. Multiply the current error by an error coefficient then add the predicted variation to obtain a current variation to obtain a current variation. Finally, obtain duty ratios of a plurality of switches, according to the current variation and inductance of the first to the third inductor. The three-phase current converter converts electric power between a DC terminal and three-phase terminals, according to the duty ratio.
