摘要
CLLLC-type DC-DC converter (CLLLC converter) has garnered significant attention due to its capability to step-up and step-down voltage in both forward and reverse directions, while maintaining consistent operating characteristics, soft switching across the full-load range, and high efficiency. Conventional control methods, such as Proportional-Integral (PI) control, are widely used due to their simple structure and straightforward principles. However, these approaches heavily depend on the model accuracy, which can lead to suboptimal performance in the presence of parameter mismatches and disturbances. To overcome this limitation, this paper proposes a comprehensive control framework for voltage closed-loop regulation and introduces the ultra-local model-free pulse-frequency modulation (UMF-PFM) approach. In this framework, the frequency and output voltage are used as variables in frequency modulation. This enables the identification of the unknown nonlinear term, which encapsulates all relevant structural information. By adjusting the frequency, the controller’s performance remains robust, reducing its dependence on model accuracy. Simulation results validate the effectiveness and correctness of the proposed scheme.
