Power transmitter and wireless power transmission system

摘要

A power transmitter 50 is usable in a wireless power transmission system for transmitting power wirelessly. The power transmitter 50 includes a power transmitting section 51 for transmitting power; a communication section 52 for communicating information, for controlling the transmission of the power, with the power receiver 60; and a control section 53 for controlling the power transmitting section 51 such that the power to be sent out by the power transmitting section 51 is higher while the communication section 52 is performing the communication.

主权项

1. A power transmitter usable in a wireless power transmission system for transmitting power from the power transmitter to a power receiver wirelessly, the power transmitter comprising:
a power transmitting section for transmitting power; a communication section for communicating information, for controlling the transmission of the power, with the power receiver; and a control section for controlling the power transmitting section such that the power to be sent out is higher while the communication section is performing the communication than while the communication section is not performing the communication, wherein: the power transmitting section transmits the power to be transmitted after converting the power into a pulse train; and the control section controls the power transmitting section such that at least one of a pulse width and a pulse amplitude of the pulse train is larger while the communication section is performing the communication than while the communication section is not performing the communication.
