Simulation Research on Current Tracking PWM Inventor Based on PSIM

电流跟踪控制技术是一种重要的PWM控制方式，具有动态响应速度快，容易实现的特点。本文利用PSIM强大的仿真功能搭建了滞环比较器仿真模塑，在分析其工作原理的基础上实现了单相和三相电流跟踪型PWM逆变器的建模仿真研究。

The current tracking technique is an important PWM control method and with the virtue of rapid dynamic response and easy to realize. With the strong simulation capability of PSIM, the hysteretic comparator model is established and its principle is discussed. By doing this, the single and three-phase current tacking PWM inventor are also modeled and simulated. From the simulating result, we can find that the inventor with hysteretic comparator has the virtue of fast current responsibility and real time tracking capability.
