Title: Shi-en Wang: Innovator in Power Supply Technology
Introduction
Shi-en Wang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of power supply technology, holding 2 patents that showcase his innovative approach to improving reliability in power systems.
Latest Patents
Wang's latest patents include a "Power Supply Unit and Calibration Method to Improve Reliability." This invention features a power supply that consists of a boost converter, a capacitor, a step-down converter, and a control unit. The boost converter converts an input voltage into a boost voltage when activated. The capacitor maintains a bulk voltage equal to the boost voltage during this activation. The step-down converter then converts the boost voltage into a step-down voltage for output. The control unit samples the input voltage and bulk voltage while the boost converter is deactivated, calculating an estimated value to determine a calibration parameter. When activated, the control unit calculates a calibration value to enable the boost converter to convert the input voltage based on this calibration value.
Another significant patent is the "Power Supply System and Control Method Thereof." This control method involves several steps. In step (A), while the power supply system provides electricity to a load, a control circuit determines an estimated capacitance value related to an output capacitor. In step (B), while the output capacitor supplies electricity to the load, the control circuit calculates an average power value related to the electricity provided. In step (C), the control circuit determines an estimated hold-up time value based on a predetermined target voltage, a minimum voltage value, the average power value, and the estimated capacitance value.
