Title: Kuo-Hsiang Chang: Innovator in Power Supply Technology
Introduction
Kuo-Hsiang Chang 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 energy solutions.
Latest Patents
One of his latest patents is for an uninterruptible power supply (UPS). This UPS includes a rectifier, a buck converter, a solar energy module, a boost converter, a controller, and a power distribution unit (PDU). The solar energy module receives solar energy and converts it to a first DC voltage. The controller compares this first DC voltage with a preset voltage and outputs a control signal to turn the boost converter on or off. When the boost converter is turned off, the rectifier receives an AC voltage from the AC power source and converts it to a rectified DC voltage, which is then output to the buck converter. When the boost converter is turned on, it converts the first DC voltage to a second DC voltage. The buck converter then converts either the rectified DC voltage or the first DC voltage to a working DC voltage, which is supplied to a power supply unit through the PDU.
Another significant patent by Kuo-Hsiang Chang is for an alternate current rectifier circuit. This circuit includes a first diode, a second diode, a first transistor, a second transistor, a third transistor, and a fourth transistor, all designed for power saving. During a positive half cycle of the alternate current, the first transistor and the fourth transistor are switched on, allowing the alternate current to flow through the first diode, the first transistor, and the fourth transistor. Conversely, during a negative half cycle, the second transistor and the third transistor are activated, enabling the current to flow through the second diode, the second transistor, and the third transistor.
