摘要 |
A power supply apparatus comprises a combined power source composed of a plurality of power cells configured electrically independently, a switch for arbitrarily connecting each of the power cells by selectively connecting terminals of the power cells through switching elements, a voltage detector for respectively detecting differences in potentials between the terminals of the power cells, a voltage regulator for stabilizing a voltage supplied to a load, a current detector for detecting a load current supplied to the load, and a controller for controlling ON-OFF states of the switching elements by controlling the switch by a control signal generated based on voltage signals on the voltages detected by the voltage detector, a power consumption of the load, and an output power of the combined power source. |
