摘要
In today's power electronic devices, power converters are widely applied in daily life, with increasing power demands. Consequently, the dynamic performance of power converters has become significant, as the compensators directly impact the system's transient and dynamic response. This paper aims to design a type-III compensator for non-ideal buck converters to improve dynamic performance over a wide input voltage range. This paper introduces the non-ideal buck converter's small signal model with state space averaging method, provides the guidelines for pole and zero positions of a type-III compensator using Matlab/Simulink Sisotool software, and presents simulation and experimental results to verify a design example and the performance and feasibility of the type-III compensator. Additionally, the transient and dynamic performance under different input voltages, load transients, and phase margins are compared with the K-factor and pole/zero compensation methods, providing a comprehensive reference when designing the compensator circuit for power converters. The results demonstrate that the designed type-III compensator effectively enhances stability and transient response, making it a valuable tool for engineers seeking to optimize power converter performance in various operational scenarios.
