Automatic disconnect of an AC source from a converter
First Claim
1. A system for automatic AC disconnect of a converter comprising:
- a converter comprising a power supply capable of being connected to an alternating current (AC) power source and converting an AC voltage to a direct current (DC) voltage; and
a portable device comprising a rechargeable battery, the portable device using the DC voltage to charge the rechargeable battery, and the portable device generating a disconnect signal responsive to the rechargeable battery reaching a full charge,wherein the connection of the portable device with the AC power source is triggered to be disconnected responsive to receiving the disconnect signal to indicate the rechargeable battery reaching a full charge.

Abstract
A system for automatic disconnect of an AC source from a converter that includes a converter and a converter. The converter includes a power supply capable of being connected to an alternating current (AC) power source and converting an AC voltage to a direct current (DC) voltage. The portable device contains a rechargeable battery where the portable device uses the DC voltage to charge the rechargeable battery. The connection of the converter to the AC power source is automatically disconnected responsive to the rechargeable battery reaching a full charge or the portable device being disconnected from the converter and automatically reconnected responsive to the rechargeable battery being below a full charge or the portable device being reconnected to the converter.
