Wireless power supply system for supporting multi remote devices

A wireless power supply system, providing a wireless electrical power adapted for a plurality of remote devices, the system comprising:

• a plurality of primary coils, wherein each of the primary coils is able to wirelessly transmit the wireless electrical power to the remote devices, the numbers of windings of the primary coils are different from each other;
• a wireless communication receiver, receiving a power requirement information;
• and
• a controller, coupled to the wireless communication receiver and the primary coils, selecting at least one of the primary coils to wirelessly transmit the wireless electrical power in accordance with its internal program;
• Wherein when a specific remote device of the remote devices is disposed to the position of the primary coils and the specific remote device sends a power identification signal, the wireless communication receiver receives the power identification signal, and performs a decode procedure to obtain a decoded power identification signal, and the controller selects a specific primary coil of the primary coils to output a corresponding wireless electrical power to the specific remote device in accordance with the decoded power identification signal.
