A Study on PWM Hybrid DC-DC Converter for Renewable Energy System
摘要
The PWM-hybrid converters are mostly used in renewable technology applications. To better understand, the process involves integrating two or more energy sources with storage systems. Using a single storage element improves both reliability and efficiency. Several methods are used to control the converter in order to lower output voltage ripple. Ripple voltage can be decreased by using a process three leg rectifier method. Voltage stress across switches and ripple voltage are decreased by using a non-isolated DC-DC converter. As a result, there will be more phases and parts. A PWM-hybrid non-isolated single switch DC-DC converter for photovoltaic applications was presented in the paper. With just one power switch, the proposed converter combines conventional Cuk and boost converters in tandem to offer continuous current mode operation. As a result, the regulated switch and diodes experience less voltage stress. Its advantages include a simple shape, great power density, and enhanced efficiency. The research shows the process of operation and on steady state exploration and their design features were discussed.
