摘要
以一种新型的PWM控制器ISL6752为核心,对其控制机理进行分析,在Simplorer7.0仿真平台基础上建立了ISL6752内部振荡模块、PWM产生模块、延迟或前置等关键模块的模型,以一台48 V/20 A的原理样机为例,进行理论设计与系统综合仿真,其模型对于原理性分析以及整定控制网络的参数具有重要的指导价值。
Taking a kind of new PWM controller ISL6752 as core,the control mechanism is analyzed.On the Simplorer7.0 simulation platform,the ISL6752 inner oscillator module,the PWM creation module,delay or leading the key module are built up.Taking a principle set of the 48 V/20 A as an example,the theoretical design and system integration simulation are carried out.The model has important instructive value to analyze and settle parameter of control network.
