摘　　要：电流滞环跟踪控制是一种重要的功率变换器电流非线性控制技术,在PSIM仿真软件中采用硬件模块设计了电流滞环跟踪方法;为解决PSIM中的高级控制算法过于复杂的问题,设计了基于软件编程的滞环实现方法,并以简化C模块为例阐述该方法的实现过程,并给出了仿真结果。在仿真设计的基础上,基于可编程逻辑器件GAL,设计了一种带有死区控制的硬件电流滞环控制电路,阐述了电流比较、滞环发生和死区控制的实现原理,实验方法验证了其有效性。Current hysteresis tracking control is an important non-linear control technology in converters.The hysteresis tracking method is designed by using hardware module in PSIM simulation software.Due to some advanced control algorithm in PSIM is too complicated to be realized by basic modules,a hysteresis implementation method based on software programming is presented.And an example based on the simplified C module is given;the simulation result is also presented.On the basis of the simulation design,by using programmable logic device GAL,a hardware current hysteresis control circuit with dead zone control is designed,the realization principle of current comparison,hysteresis generation and dead zone control is also given.At last,this method is validated by experiment.
