FEED UNIT AND FEED SYSTEM
First Claim
1. A feed unit comprising:
- a power transmission section configured to perform power transmission with use of a magnetic field or an electric field;
a power limiting section provided on a power supply line from an external power source to the power transmission section; and
an operation stop section configured to forcibly stop the power transmission, whereinthe operation stop section forcibly stops the power transmission when a voltage between an input and an output of the power limiting section exceeds a first threshold, andthe power limiting section forcibly interrupts power supply to the power transmission section when the voltage between the input and the output exceeds a second threshold, the second threshold being larger than the first threshold.

Abstract
A feed unit includes: a power transmission section configured to perform power transmission with use of a magnetic field or an electronic field; a power limiting section provided on a power supply line from an external power source to the power transmission section; and an operation stop section configured to forcibly stop the power transmission. The operation stop section forcibly stops the power transmission when a voltage between an input and an output of the power limiting section exceeds a first threshold. The power limiting section forcibly interrupts power supply to the power transmission section when the voltage between the input and the output exceeds a second threshold that is larger than the first threshold.

19. A feed system provided with one or a plurality of electronic apparatuses and a feed unit configured to perform power transmission on the electronic apparatuses, the feed unit comprising:
-
a power transmission section configured to perform the power transmission with use of a magnetic field or an electronic field; a power limiting section provided on a power supply line from an external power source to the power transmission section; and an operation stop section configured to forcibly stop the power transmission, wherein the operation stop section forcibly stops the power transmission when a voltage between an input and an output of the power limiting section exceeds a first threshold, and the power limiting section forcibly interrupts power supply to the power transmission section when the voltage between the input and the output exceeds a second threshold, the second threshold being larger than the first threshold.
