Abstract
A wireless charger equipped with an auxiliary power supply includes a power input unit which is connected to an external power supply, a wireless power transmission unit which wirelessly transmits electrical power to an electronic device through a magnetic field, and an auxiliary power unit which charges a battery provided therein with electrical power supplied from the power input unit, or charges the battery and, at the same time, provides the electrical power to the wireless power transmission unit, and provides the electrical power of the battery provided therein to the wireless power transmission unit when the power supply from the power input unit is stopped.
Claims10
A wireless charger including an auxiliary power supply, the wireless charger comprising:
- a power input unit which is connected to an external power supply;
- a wireless power transmission unit which wirelessly transmits electrical power to an electronic device through a magnetic field;
- and
- an auxiliary power unit which charges a battery provided therein with electrical power supplied from the power input unit, or charges the battery and, at the same time, provides the electrical power to the wireless power transmission unit, and provides the electrical power of the battery provided therein to the wireless power transmission unit when the power supply from the power input unit is stopped.
A wireless charger including an auxiliary power supply, the wireless charger comprising:
- a first power input unit;
- a second power input unit;
- a wireless power transmission unit which converts electrical power, supplied from the first power input unit or the second power input unit, into a magnetic field and charges an electronic device;
