Research on efficiency optimization control technology for distributed interleaved parallel power supply systems

This paper proposes a new method for the efficiency optimization control of the distributed interleaved parallel power supply systems (DIPPS). The proposed method uses a fuzzy logic controller (FLC) to dynamically adjust the switching frequency and the duty cycle of the converters, based on the load current and the input voltage. The proposed method can handle the nonlinear and uncertain characteristics of the DIPPS, and can achieve fast and smooth control performance. The proposed method can also adapt to the load variation and the input voltage variation, and can optimize the efficiency of the DIPPS under different operating conditions. The proposed method can avoid the complex mathematical derivation and the high computational complexity of the conventional methods, and can simplify the implementation and the tuning of the controller. The effectiveness and the superiority of the proposed method are validated by extensive experiments, compared with the existing methods, under various test scenarios.
