Title: John V Swenson: Innovator in Power Supply Systems

Introduction

John V Swenson is a notable inventor based in Oronoco, MN (US). He has made significant contributions to the field of power supply systems, particularly through his innovative patent that addresses battery back-up control.

Latest Patents

Swenson holds a patent for a "Method of controlling battery back-up for multiple power supplies." This invention involves a power system that includes a battery back-up unit (BBU) with back-up battery circuitry. The BBU provides battery back-up support for multiple power supplies, each equipped with a power factor correction circuit front-end featuring a boost stage. The system monitors the output voltages from the boost stages and compares them with reference threshold voltages. This process generates a signal to activate the battery back-up power when a monitored voltage drops below a certain threshold, indicating a potential loss of AC mains input voltage. Additionally, the system monitors the AC mains input voltage to detect restoration and disconnect the battery back-up power when appropriate. If the battery back-up is activated due to a faulty power supply, the system can mask the faulty supply and report it for repair.
