Patent ID: 7847528

Claim:
A single-board power supply structure, comprising: an operational processor and at least two DC/DC converters (C) connected with the operational processor, wherein the operational processor is adapted to send Pulse-Width Modulation (PWM) control signals to the DC/DC converter (C), for controlling the output of the power supply of the DC/DC converter (C), monitor the output of the power supply of the DC/DC converter (C), and adjust the output of the power supply of the DC/DC converter (C) according to the monitored result by sending a PWM control signal; and the DC/DC converter (C) is adapted to convert a received bus voltage into power supply voltage required by the single-board according to the received PWM control signals; wherein the PWM pulse respectively drive the DC/DC converters to convert low bus voltage into at least two power supply voltages required by the single-board; the operational processor is further adapted to control the sequence of the outputs of the power supply converted by the DC/DC converter (C) by controlling the time for sending the control signals; and the at least two DC/DC converters (C) comprising a non-isolated DC/DC converter and/or an isolated DC/DC converter, the non-isolated DC/DC converter comprising a non-isolated buck DC/DC converter and/or a non-isolated boost DC/DC converter, and the isolated DC/DC converter comprising an isolated buck DC/DC converter and/or an isolated boost DC/DC converter.
