Title: Jiong Ou: Innovator in DC-DC Converter Technology
Introduction
Jiong Ou is a notable inventor based in Baden Wuerttemberg, Germany. He has made significant contributions to the field of electrical engineering, particularly in the area of DC-DC converters. With a total of 3 patents to his name, his work focuses on enhancing the efficiency and performance of power conversion systems.
Latest Patents
One of Jiong Ou's latest patents is a method, system, and apparatus for suppressing controller area network bus ringing. This innovation involves CAN bus drive slew rate control, which is utilized to suppress ringing through bus impedance matching. This system is activated during and shortly after the bus driver unit transitions from a 'dominant' to a 'recessive' state. In one embodiment, the bus impedance matching unit is a differential input and output operational trans-conductance amplifier (OTA). This differential OTA effectively absorbs or provides the ringing current based on the bus differential voltage. Another embodiment features a back-to-back connected regulated transistor pair along with a gate control circuit, where the total resistance equals the CAN bus characteristic impedance.
Another significant patent by Jiong Ou involves a method, system, and apparatus for constant, high switching frequency and narrow duty ratio PWM control of DC-DC converters. This innovation includes current-starved delay lines for phase-shifting control signals that set and reset an RS flip-flop, allowing for controllable PWM pulse widths. The system ensures precise pulse width control and a guaranteed minimum pulse width for pulse frequency modulation (PFM) control during low power demand. PFM control maintains a consistent pulse width while adjusting the number of pulses per second based on the output voltage levels.
