As a basic DC/DC step-down converter circuit, Buck converter is widely used in continuously variable transmission technique and control of motor. Based on the PSpice software, the circuit simulations including the pa- rameters simulation, power analysis and absorption circuit design are developed for Buck converter in this paper. By visualization teaching, the influence on the circuit performance with different Buck circuit parameters can be ob- served and analyzed visually and it provides reliable basis for actual circuit design, research and development.
