PWM Rectifier Model with Hysteresis Control Implemented Using Hysteresis Comparator

This paper introduces a novel PWM rectifier model that implements hysteresis control through a hysteresis comparator. The model is applicable to various electronic devices such as power supplies and motor drives. We provide a comprehensive breakdown of the model construction process and explain how to control PWM signal output using the hysteresis comparator. The implementation typically involves comparing the actual current with reference values using a dual-threshold approach, where the comparator switches states when the error exceeds predefined upper and lower limits. Additionally, we discuss the model's advantages, application scenarios, potential issues, and corresponding solutions. Key functions include real-time error calculation and dynamic PWM duty cycle adjustment based on the hysteresis band. Through this paper, readers can gain in-depth understanding of the working principle and implementation methodology of this PWM rectifier model, providing valuable references and insights for related research fields.
