Abstract	To meet the high power and high stability requirements of BWT 915-10W and 915-30W pumped semiconductor laser (with adjustable current from 0 to 12A, current ripple factor less than 2%) a dual control and dual output circuit is designed to allow the power supply output current adjustable from 0 to 12A. It is called dual control because power can control manually by an external knob to achieve current continuously adjustable, and also through DSP28035 to achieve current digital regulation. Temperature detection with protection circuits is also designed, and so is highly reflective pulsed light detection with protection circuits. The output state of the DSP is controlled by signals from the control card. They communicate each other through A 25-pin parallel port. By designing schematics, producing PCB and repeated tests, it is indicated that this dual power supply is a small ripple, high stability and efficient, small volume and light weight switching power supply.
