Beschreibung
Zusammenfassung:	A wireless charging system (10, 20) is provided. The wireless charging system (10, 20) includes a wireless power supply platform (100, 300), a first device (200_1, 200_2, 400_1, 400_2), and a second device (200_1, 200_2, 400_1, 400_2). The wireless power supply platform (100, 300) provides a wireless suppling power (WP). The first device (200_1, 200_2, 400_1, 400_2) includes a first power receiving circuit (210_1, 210_2, 410_1, 410_2), a first power switch (SW1, SW2), and a first control circuit (220_1, 220_2, 330, 420_1, 420_2). The second device (200_1, 200_2, 400_1, 400_2) includes a second power receiving circuit (210_1, 210_2, 410_1, 410_2), a second power switch (SW1, SW2), and a second control circuit (220_1, 220_2, 330, 420_1, 420_2). The second control circuit (220_1, 220_2, 330, 420_1, 420_2) communicates with the first control circuit (220_1, 220_2, 330, 420_1, 420_2) to determine a coordinated switching state of the first power switch (SW1, SW2) and the second power switch (SW1, SW2). The coordinated switching state determines a first output voltage value (VO1, VO1_1~VO1_4, VO2, VO2_1~VO2_4) generated by the first power receiving circuit (210_1, 210_2, 410_1, 410_2) according to the wireless suppling power (WP) and a second output voltage value (VO1, VO1_1~VO1_4, VO2, VO2_1~VO2_4) generated by the second power receiving circuit (210_1, 210_2, 410_1, 410_2) according to the wireless suppling power (WP).
