| Abstract: | Considering the current development of switching power supply, a schene under high frequency and power was analyzed and studied. The main circuit and control circuit of 20 kHz/3 kW power supply were theoretically designed and their parameters were estimated. After simulated by PSPICE, this system turns out paractical and its performance can meet the design requirements |
