Title: Innovations by Inventor Kai Yao
Introduction
Kai Yao is a notable inventor based in Nanjing, China. He has made significant contributions to the field of electrical engineering, particularly in the development of driving apparatuses for light-emitting diodes (LEDs). With a total of 3 patents, his work showcases innovative solutions that enhance the efficiency and functionality of electronic devices.
Latest Patents
One of his latest patents is a driving apparatus for light-emitting diodes without employing an electrolytic capacitor. This apparatus is designed to drive at least a string of LEDs and includes a flyback power factor correction (PFC) converter, a harmonics-filtering unit, and a control unit. The flyback PFC converter operates according to a pulse-width modulation (PWM) signal, converting AC power into a pulsating current. The harmonics-filtering unit filters out high-frequency harmonic components, ensuring the LEDs are driven effectively. The control unit generates the PWM signal to reduce the peak-to-average ratio of the pulsating current.
Another significant patent involves a means of eliminating the electrolytic capacitor as the energy storage component in a single-phase AD/DC two-stage converter. This power factor correction circuit utilizes an inductor, a diode, a storage capacitor, a switch, and a control unit. The circuit absorbs voltage fluctuations, resulting in a reduced energy storage capacitance. This innovation allows for a more efficient power management system.
