Abstract

PURPOSE:To stabilize the supply of maximum electric power to a load by controlling a power converting circuit after discriminating the coincidence or dissidence between the polarity code of secular change's share of the output electric power of a solar battery array, and the corresponding code of the output voltage. CONSTITUTION:A load 2 is connected to a solar battery array 1 via a power converting circuit 3. The voltage V and the current I of an output voltage detecting print Pv and an output current detecting part Pi of the array 2 are supplied to a power change detecting circuit 7 consisting of a multiplier 4, a sample holding circuit 5 and a divider 6. Then the control is carried out so that the maximum supply power is secured for the circuit 3 via a control circuit 8. Here a logical circuit 9 is connected to the divider 6 together with addition of a voltage change detecting circuit 10. A polarity code comparing/ deciding circuit 13 is formed with the circuit 9 and the circuit 8. Then the circuit 13 discriminates the polarity between the voltage and power change signals SV and SP, and the voltage increase/decrease signals are outputted with the coincidence/discordance comparison signal St.
