Patent ID: 7932631

Claim:
A power allocating apparatus applied in a plurality of power supply modules, wherein the plurality of power supply modules are coupled to a plurality of loads via a plurality of power lines, respectively, the power allocating apparatus comprising: a first switch element, having a first connecting terminal and a second connecting terminal coupled to a first output terminal of at least one of the plurality of power supply modules with a first power conversion rate and a second output terminal of at least one of the plurality of power supply modules with a second power conversion rate, respectively, for selectively allocating a power generated by the power supply module with the first power conversion rate to a predetermined number of loadings simultaneously according to on or off states of the first switch element; and a control device, coupled to the first switch element, for generating the control signal to control the first switch element to enter an on state or an off state; wherein the first power conversion rate is higher than the second power conversion rate; wherein the power supply module with the second power conversion rate is turned off when the first switch element is under the on state.
