Design and simulation of photovoltaic hydrogen production converter based on dual-loop control
Converters are important devices for achieving photovoltaic power generation suitable for hy-drogen production systems.Therefore,studying converter related technologies has significant practical value and theoretical significance.This article studies the photovoltaic hydrogen production converter and the dual loop control method.Firstly,calculate the component parameters of the Boost circuit and the Buck Boost cir-cuit according to the requirements of the photovoltaic hydrogen production system.Then,the control circuit of the photovoltaic power generation module was designed to increase the output voltage of the photovoltaic array by controlling the on and off of the IGBT in the Boost circuit,enabling it to reach the maximum power point.Design a dual loop control strategy based on the combination of current loop and voltage loop to control the conduction and shutdown of switches in the circuit,ensuring the stability of system output voltage and power.The control circuit of the energy storage module controls the on and off of the IGBT in the Buck Boost circuit to charge and discharge the battery and maintain stable bus voltage.The control circuit of the battery adopts dual loop control,which makes the control accuracy of the photovoltaic hydrogen production system higher.After completing the design,build a simulation model of the photovoltaic hydrogen production system,observe the output waveform of the system under different conditions,and verify the feasibility of the design.
