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.
