摘要
简要介绍了PWM型DC-DC开关变换器的基本类型及其原理,回顾了对其建模和控制的有关应用和发展情况,展望了开关变换器的未来发展。同时指出:如何建立精确的数学模型并在此基础上寻求好的控制策略是研究DC-DC变换的一个关键。
A brief view of the basic principle of DC-DC switching power converters was given. Applications and developments of the related study on its modeling and controlling were reviewed and the future in this field was presented. Based on above expatiation, it was pointed out that how to establish the precise mathematic model and how to search for a good control strategy are a key problem for the research of DC-DC inverting.
