Abstract

To adapt the output voltages of PV systems and fuel cells to the voltage levels required by grid-connected power generation systems. In this paper, a high-gain DC-DC converter based on single-neuron PID is proposed. The boost unit based on coupled inductance enables the converter to add a new degree of freedom to the original switching duty ratio D, to adjust the output voltage. The introduction of clamped units reduces leakage from coupled inductors and voltage spikes in semiconductor devices, and increases the efficiency of the converter. The jamming capability of the converter is enhanced by a single-neuron PID. In this paper, we analyze the mode of operation of the proposed converter, introduce its performance characteristics, and compare it with classical converters. The validity of theoretical analysis and the precision of experimental procedures are confirmed through circuit operation simulations and experimental modeling.
