摘要： A correlated colour temperature control system (1) for a LED lighting system (2) having at least two LED sources (3, 4) with different correlated colour temperatures. The LED lighting system (2) has a combined correlated colour temperature resulting from the combination of the different correlated colour temperatures of the at least two LED sources (3, 4), and a combined luminous flux resulting from the combination of the luminous fluxes of the at least two LED sources (3, 4), with each LED source being supplied with a supply current. The correlated colour temperature control system (1) comprises a controller (5) to independently control one or both of the duty cycle and amplitude of each supply current, the duty cycle or amplitude of each supply current being varied by the controller in a non-linear relationship with the duty cycle or amplitude of at least one other of the supply currents, to generate a desired combined correlated colour temperature for the LED lighting system (2) at a desired combined luminous flux for the LED lighting system (3, 4). An associated method is also provided.

摘要： Provided is coordinated control and use of a transmitter circuit and a receiver circuit for wireless battery charging, with emphasis on using power switches in the receiver circuit not only for handshaking with the transmitter circuit for compatibility check and communication of information but also for charging mode control of the battery. It utilizes extra switching operations of power switches in the receiver circuit (such as those commonly used in the Qi standard for handshaking with the transmitter circuit) to charge the battery directly from the output of the rectifier with the constant-current mode or constant-voltage mode according to a threshold battery voltage without using an extra battery management circuit between the rectifier of the receiver circuit and the battery. Coordinated operations of the transmitter and receiver circuits can be achieved without using any extra wireless communication system for signal synchronization between the two circuits.

摘要： A battery charging system determines a current condition of a battery in real time and dynamically determine a threshold voltage for controlling a charging mode of the battery based on the current battery condition. The battery charging system charges the battery using a constant current (CC) mode or constant voltage (CV) mode based on the battery voltage and the dynamically determined threshold voltage. The battery charging system can determine the voltage and current of the battery in real time without receiving information on the battery from the power receiving side of the battery charging system.
