Abstract

PURPOSE: To increase overall efficiency in DC conversion, by connecting each terminal of a converter so that the sum of the output voltage and the input voltage of a DC/DC converter can be supplied to the load.
CONSTITUTION: DC current from solar cell 1 and secondary battery 3 is supplied to load 9 via DC/DC converter 5. Output terminal d is connected to input terminal a of converter 5. Further, input terminal b is connected to one terminal of load 9. By this, a conversion efficiency larger than that in the case where only converter 5 is used is obtained. Terminal e is to control output voltage V2. When load 9 is FET, in order to establish gate voltage before drain voltage is established, output voltage V2 is checked from becoming large by opening switch 8 until the output voltage (gate voltage) from converter 6 reaches a preset value.
