Research of Practical Solar Energy Intelligent Regulated Power Supply

Abstract:

A solar-powered fuzzy PID control based DC/DC series the LDO method is suggested to take advantage of the performance of the DC/DC converter high efficiency while reduce the output ripple and low voltage is continuously adjustable. Fuzzy PID control according to the error of sampling the output voltage and the desired output voltage, the DC/DC output and LDO output with constant pressure difference control. The circuit structure, the dynamic response of output voltage in the process of abrupt change of load and starting is analyzed. Parameter selection and design considerations are given. A BUCK converter is used as an example to show the design steps. Simulation study are made on the supply, the results of which show that method is feasible
