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 comprising circuitry provided on a power supply line from an external power source to the power transmission section; and
an operation stop section comprising a switching circuit 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, andthe circuitry of the power limiting section is configured to forcibly interrupt power supply to the power transmission section in an event that 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.
