Japanese Patent JP7146027
Kind Code:
B2
Abstract:
To transmit optimum power even when a load fluctuates.SOLUTION: A power transmission device 10 includes power transmission means (coupler 12) for transmitting power to a power reception device. The power reception device includes: power reception means (coupler 21) for receiving power transmitted from the power transmission means of the power transmission device; rectification means (rectifier 23) for rectifying power received by the power reception means to DC power; matching means (matching unit 22) for performing impedance matching before and after the matching means, the matching means disposed between the power reception means and the rectification means; conversion means (SW converter 24) for receiving input of DC power obtained by the rectification means and supplying DC power having different voltage converted by switching to a load; and power reception side control means (power reception side control unit 26) for controlling a duty ratio of switching of the conversion means so that input resistance of the conversion means has a predetermined value.SELECTED DRAWING: Figure 1
