    Abstract: A power transmission system includes: a power transmitter connected to a power supply; a plurality of power receivers respectively connected to a plurality of loads; a power transmission line connecting the power transmitter and the plurality of power receivers; and a controller. The controller acquires information on optimum power for maximizing transmission efficiency in the power transmission line and information on power demands requested by the loads, and routes transmission power from the power transmitter selectively to the plurality of power receivers. The transmission power is equal to or smaller than the optimum power. When a total power demand is larger than the optimum power, the controller requests another controller to supply supplementary power. When the total power demand is smaller than the optimum power, the controller notifies the other controller that surplus power is available.

    Abstract: A power converter includes a transformer including a transformer including a primary winding and a secondary winding magnetically coupled to the primary winding, a bridge circuit including a switching element, and an inductor. A direct current voltage is converted into an alternating current voltage by turning on and off the switching element in the bridge circuit. An output voltage in the secondary winding is induced by supplying the alternating current voltage to the primary winding. The inductor is disposed on a path connecting the switching element and the primary winding. A resonance inductance value Lr including a leakage inductance value of the transformer and an inductance value of the inductor satisfies Formula 1.
