Abstract

PURPOSE:To effectively utilize a power source by producing an AC voltage before converting to DC voltage to obtain a logic sum with other power source, rectifying the output to obtain a DC power source, thereby eliminating the coupling loss of the two power sources. CONSTITUTION:When two power sources 6, 7 which output DC voltages A, A' are coupled to obtain another DC voltage B, AC voltages (1), (2) before obtaining the DC outputs A, A' of the power sources 6, 7 are produced, and the logic sum of them is obtained. A calculator for obtaining the logic sum is formed of diodes D7, D8. The output is rectified by a rectifier (of diodes D7, D8. The output is rectified by a rectifier (of diodes D7, D8 and a capacitor C3) to obtain the DC output B. Thus, since the coupling loss can be reduced as compared with the case that the DC outputs are coupled, an internal battery E can be increased in its lifetime.
