Abstract
Official abstract text for this publication.
A power supply module coupled with a primary winding of a power conversion module, the power supply module includes a plurality of power-controlling modules, a plurality of second switches, and a microprocessor. Each power-controlling module includes an auxiliary winding and a first switch electrically connected in series, and each auxiliary winding is magnetic coupled with the primary winding. Each second switch is electrically connected to one of the power-controlling units. The microprocessor is electrically connected to the first switches of the power-controlling modules and the second switches. The microprocessor places at least one first switch and one of the second switches in a conducting state to make the first switch in the conducting state and the second switch in the conducting state electrically connect in series and output an electric power to power the power conversion module.
