Title: Chih Hung Chiang: Innovator in Power Supply Systems

Introduction

Chih Hung Chiang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of power supply systems, particularly with his innovative approach to ensuring uninterrupted power to protected load devices.

Latest Patents

Chiang holds a patent for a "Power supply failover system and method." This invention provides an uninterruptible power supply to protected load devices (PLD). The system includes a failover switch controller (FSC) that receives inputs from an AC I/V monitor (AIV), an AC cycle counter (ACC), a failover switch timer (FST), and an overcurrent protection timer (OPT). The FSC uses these inputs to manage the failsafe switching of a bypass phase switch (BPS) and an AC phase switch (ACS) to the PLD when the power from the APS is deemed reliable by the AIV. If the AIV detects compromised power from the APS, the FSC disables the ACS/BPS and activates a DC switch (DCS) and a battery isolation switch (BIS) to connect a DC source to the PLD after a predetermined time set by the FST. The overcurrent protection for APS/DCS is regulated by OPT intervals, facilitating a smooth transition between the APS and DCS during power failover and failback.
