| Abstract: | According to the voltage gain of the traditional photovoltaic boost effect was not good and unstable when input voltage changes, and the output power quality was not high, a combined photovoltaic boost DC - DC con- verter circuit were proposed. The boost circuit principle was detail analyzed, and the algorithm was given to comple- ment the circuit control. This circuit has the following characteristics ： 1 ） The gain of the boost circuit was better, the voltage gain of about 4.5 ;2） The output voltage gain was stable when the input voltage changes ;3 ） The output power quality was high ,and voltage fluctuation percentage was about 1.5% ;4） The control of the circuit was simple |
