PURPOSE:To prevent an increment of overall size of a device by setting the number of parallel connections of solar batteries at a prescribed level for a solar battery circuit and therefore reducing the overall power consumption of each shunt circuit and an error voltage detecting amplifier. CONSTITUTION:The number of parallel connections of solar batteries is set for solar battery circuits 2a-2c so as to obtain an equal sum of the power consumption of shunt circuits 5a-5c and the power consumption of an error voltage detecting amplifier 4 in case the power consumption of the circuits 5a- 5c is maximum. Thus the total power consumption of the circuits 5a-5c and the amplifier 4 can be reduced, and therefore the heating value is reduced to prevent an increment of overall size of a device. |
