摘要：The present invention discloses a high-efficiency power supply device and itscontrol method. The power supply device includes a power conversion circuit and a loadbalance detection circuit. The power conversion circuit is connected to at least one set of
switch module through an electric circuit, a resistor connected in parallel with the switchmodule, and a power output load terminal for driving a load. The load balance detectioncircuit is connected to the power conversion circuit and the switch module, such that theload balance detection circuit can detect whether or not a load driven by one or moresets of power output load terminals is balanced. If the driven load is not balanced, thenthe one or more sets of resistor will be in a closed circuit status to achieve a load balance.
