Abstract:

Traditional analog-controlled DC/DC converter can only employed easy control method and always has complicated hardware structure. Its extremely unfavorable in improving efficiency and reducing the cost of hardware. In this paper, a new full digital control method has been proposed. This method employed an advanced main circuit topology combining with an ARM MCU, it can reduce power supplys volume and cost, improve its efficiency effectively. The Topology of main circuit is reasonable, the design of parameters was right. All the results were consistent well with theory analysis. The power supply can realize leading legs ZVS and lagging legs ZCS in a big load range. The whole system has concise hardware structure, reliable control method and good man-machine interface, so it has high practical value.
