摘要:

针对电流控制离散脉冲调制方式下的一种软开关组合式变换器,借助于时域仿真和付里叶变换建立系统频域模型(频率特性曲线),并在此基础上导出等效解析模型,为软开关组合式变换器系统性能分析提供了一种方便可行的方法,特别是解决了其电压调节器设计盲目性的问题。并给出了电压调节器设计及系统性能分析实例。

Abstract:

Modeling and control of a Soft Switching Combination Converter which works in current controled discrete pulse modulation mode,are proposed. Firstly a model in frequency domain is built through time domain simulation and the Fourier transforming.Then based on the frequency domain model,an equivalent analytic model is established and this is important for voltage regulator design and system performance analysis of the converters.Examples are given at the end of the paper.

Key words: power conver ters, contr ol, modelling
