Abstract: A charging circuitry includes a power electronic converter, a current sensor, a voltage boost/buck controller and a charging mode controller. The power electronic converter is configured to charge or discharge a supercapacitor according to a control command. The current sensor is coupled to the supercapacitor for detecting a first sensed voltage and a second sensed voltage. The voltage boost/buck controller is configured to generate the control command and a current command according to the first and second sensed voltages and an overall feedback. The charging mode controller is configured to generate a current feedback and a voltage feedback to the voltage boost/buck controller according to a driving voltage, the current command and a third sensed voltage of the supercapacitor. The third sensed voltage, the current feedback and the voltage feedback are superposed as the overall feedback and then inputted to the same input terminal of the voltage boost/buck converter.

Abstract: An electronic transformer includes a first forward rectifier, a second forward rectifier, a third forward rectifier and a backward rectifier. The first forward rectifier is coupled between a first-phase power and a first output terminal. The second forward rectifier is coupled between a second-phase power and the first output terminal. The third forward rectifier is coupled between a third-phase power and the first output terminal. The backward rectifier is coupled between a neutral line and a second output terminal. The first forward rectifier, the second forward rectifier, and the third forward rectifier are configured to half-wave rectify the first-phase power, the second-phase power, and the third-phase power to generate rectified first-phase to third-phase power sources, and superimpose the rectified first-phase to third-phase power sources on the first output end to serve as an output voltage of the electronic transformer.

Abstract: A driving circuit, a driving method and a display apparatus are provided. The driving method is provided for driving a light-emitting unit including a first light-emitting element series and a second light-emitting element series connected in parallel and connected to a processing unit and a driving unit of a driving circuit. The processing unit detects a first voltage value and a second voltage value. The driving unit detects and transmits a first current value and a second current value to the processing unit. The processing unit determines and compares a first power value and a second power value. When the first and second power values are different, the processing unit controls the driving unit to adjust a driving current setting of the light-emitting element series until the first and second power values are equal. The invention ensures luminance consistency of different light-emitting element series and the luminance uniformity of display apparatus.
