Abstract
This paper aims to design and simulate a DC / DC converter suitable for photovoltaic systems to meet the specific performance index requirements. The converter is designed to convert a DC input voltage of 30V-40V into a stable DC output to provide a fixed capacity power of 500W and to achieve a maximum power of 700W under instantaneous conditions. To achieve this goal, this paper studies the maximum energy tracking control strategy of photovoltaic system, and analyzes the composition and working principle of DC / DC converter in detail. In this paper, we complete the hardware design and element selection of DC / DC converter, and verify the control system by using MATLAB / SIMULINK platform. By comparing and analyzing the performance of different design schemes, the optimal design scheme is finally determined, and its practical application effect in photovoltaic system is verified. The research results of this paper are of great significance for improving the energy conversion efficiency and stability of photovoltaic systems.
