Apparatus and methods for control of load power quality in uninterruptible power systems

This invention describes a system designed to provide clean and uninterrupted electrical power to sensitive equipment. It works by using a special switch, made up of multiple rectifiers, to manage power flow between the main electricity supply and a backup power source like a battery. This setup actively filters out electrical noise from the main supply, ensuring that the connected devices receive only smooth, stable power.

Why it matters: Since 2014, advancements in power semiconductor technology have made high-efficiency static converters more compact and affordable. This could enable a more cost-effective implementation of the rectifier-based static switch and power conditioning, especially for integrating with modern renewable energy systems.
