Claim 13:
14. A method of converting a three-phase AC input into a DC output in an electrical boost converter, the method comprising:
rectifying the three-phase AC input to obtain a rectified intermediate signal across an upper intermediate output node and a lower intermediate output node;
connecting a phase of the three-phase AC input having an intermediate voltage between a highest voltage and a lowest voltage of the three-phase AC input alternatingly to the upper intermediate output node and the lower intermediate output node by switching of at least one first semiconductor switch via pulse width modulation;
boosting the rectified intermediate voltage to obtain the DC output across an output filter comprising a filter capacitor, wherein boosting the rectified intermediate voltage comprises controlled switching of the rectified intermediate voltage signal through at least one second semiconductor switch via impulse width modulation to obtain a pulsed voltage signal; and
applying the pulsed voltage signal across the output filter;
wherein boost energy is stored in boost inductors connected to the three-phase AC input prior to rectifying.
