中文说明：1、文件是在Matlab2013a上创建的，较低版本可能不兼容； 2、仿真的各元件参数一调好，仿真结果双击示波器可得仿真结果波形； 3、结果波形可用语句plot(ScopeData.time,ScopeData.signals(1, number).values)重新绘制效果更好； 4、本仿真是电力电子技术常用的DC-DC变换中的升降压斩波电路仿真 5、调整触发源触发角可实现升降压斩波，输出电压和电源电压的关系为：Uo=E*a/(1-a) 注：number代表所需的画得图的代号; Uo:输出电压; E:电源电压
English Description：
1, the file is created on the Matlab2013a and earlier versions may not be compatible with; 2 the component parameters, simulation of a tuned and simulation results, double-click oscilloscope waveform simulation results available; 3, the resulting waveform plot available statements (ScopeData.time,ScopeData.signals (1 number). values) to repaint is better; 4, the simulations are commonly used in DC-DC converter power electronics technology buck chopper circuit simulation 5, adjust the trigger source trigger angle achievable buck chopper, output voltage and power supply voltage: Uo=E*a/(1-a) Note: the painted figure of the number represent
