ENERGY EFFICIENT POWER ADAPTER

摘要

According to one embodiment, an AC power adapter for providing voltage to an electrically-operated device includes a power converter module electrically coupled to a power source via at least one hot lead and at least one neutral lead. The power converter module is configured to convert voltage received from the power source to voltage suitable for use by the electrically-operated device. The AC power adapter also includes a relay circuit coupled to the hot lead to control the voltage passing from the power source to the power converter module.
