Introduction

Ching-Jan Chen is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of power management and converter technologies. With a total of 8 patents to his name, Chen's work has had a substantial impact on the industry.

Latest Patents

One of his latest inventions is the "Boost Converter Power Stage Circuit." This invention discloses a boost converter power stage circuit that includes an organic light-emitting diode power management integrated circuit unit, a switched capacitor converter, and a boost converter. The design utilizes a flying capacitor to enhance the voltage of the inductor to twice its original value, subsequently boosting the positive voltage of the output voltage source. The switched capacitor converter is then employed to output the voltage, facilitating the conversion of negative voltage.

Another notable patent is the "Timing Controller for Power Converter." This power converter comprises a power stage, a feedback circuit, a ramp generator, and a controller. The power stage generates a pulse width modulation signal to form an output voltage. The controller features a comparator, a control logic circuit, an on-time generator, and an off-time generator. The comparator produces a comparison signal based on a compensation signal from the feedback circuit and a ramp signal from the ramp generator. The control logic circuit generates a first trigger signal based on the comparison signal and an off-time pulse signal, while the on-time generator creates a duty signal to control the duty cycle ratio of the pulse width modulation signal.
