Article Preview

Abstract:

This paper study a new type of photovoltaic soft switching boost circuit according the present photovoltaic soft switching boost circuit auxiliary switch worked in hard switching situation and the gain of soft switching boost circuit is not good. The operation principle of the circuit and the detailed implementation process was analyzed. The parameters of the circuit were counted. The phase shifting control algorithm was used to control the circuit. The soft switching boost circuit has the following characteristics: (1) The main switch and auxiliary switch can realize zero current zero voltage turn-on and turn off, improve the conversion efficiency of DC side; (2) The boost effect is good and the gain is high; (3) High output power quality, voltage fluctuation is low; (4) The control is simple.
