Abstract :
Solar energy is one of the most important sources of energy because it is a renewable and inexhaustible energy. This paper presents a new energy recovery snubber for a high step-up boost converter, which can be used in renewable energy systems such as photovoltaic. The proposed snubber enjoys useful advantages such as providing soft-switching conditions, high voltage gain, simplicity of control, and balanced voltage stresses. In this topology, the voltage stress on the diodes and switches is a small percentage of the output voltage. A simple boost and a fly-forward converter are used to increase the output voltage. A snubber circuit is used for the main switch to recover the energy of the snubber capacitor. Therefore, the main switch turns off at low voltage and it causes a reduction in turn off loss. Experimental results of a 48V to 380V and 500W laboratory prototype show efficiency greater than 95% and verify the given theoretical analysis.
