Dong-Young Huh, a prominent inventor located in Bucheon, South Korea, has made significant contributions to the field of power supply technology. With a remarkable portfolio that includes nine patents, his innovative ideas are shaping the future of electrical engineering.

Latest Patents

Among Dong-Young Huh's latest inventions is a groundbreaking Switching Mode Power Supply (SMPS) designed to compensate for variations in maximum output power when faced with fluctuating input power. This invention addresses the challenge of output power variations due to propagation delays within the SMPS. By establishing a reference voltage that is adjusted according to the input voltage, the invention effectively mitigates the impact of these delays.

His inventive solution ensures that the maximum output power remains stable, regardless of the input voltage fluctuations, by differentiating the turned-off time of the reference voltage when handling the main switch—typically a switching MOS transistor.

Another innovative aspect of his work involves a power supply that provides power to the secondary coil of a transformer, dependent on the operation of the main switch connected to the primary coil. Huh's SMPS also includes a feedback circuit to generate a voltage corresponding to the output voltage, and a control module that halts the main switch during standby operation mode when the feedback voltage drops below a designated reference voltage. This design showcases an integrated circuit (IC) power unit that produces constant voltage and current for operating multiple ICs, further enhancing the efficiency and functionality of power supply systems.
