In the teaching, at present most of the schools only use test cases completed experiment teaching of electronic course, almost all of the circuit is closed. Experiments because do not understand the working principle of circuits and devices as long as a slight problem students blindly asked the teacher, is not conducive to cultivate students ability of solving problems by themselves. Due to the relevance of power electronics device itself, for power electronic circuits and analyzes the complexity and difficulty in the system, common waveform analysis and segmentation processing method to study the power electronic circuit. Modern computer simulation technology for power electronic circuits and systems analysis provides a new method, which can make the complex power electronic system analysis and design easier and effective. MATLAB as a kind of applicable to matrix operation and control and information pr
