Abstract
A power transmission system is provided. In the power transmission system, a plurality of power supply voltages are switched alternately and periodically, and is sent from an upstream module unit toward a downstream control unit as one system of output voltage. In the downstream control unit, a plurality of voltages from the inputted voltage is separated and supplied to loads, and the voltage is monitored so as to determine switching timing. Further, the downstream control unit is equipped with capacitors for each system of voltages, and thereby the voltages are maintained even during a time period when no power is supplied from the upstream module unit. A low voltage required by a CPU of the downstream control unit is generated by a voltage regulator of the downstream control unit. The power loss that is caused in generating power to be consumed by low-voltage loads can be reduced.
