System And Method For Limiting Over-Voltage In Power Supply System

Patent No. EP3083467 (titled "System And Method For Limiting Over-Voltage In Power Supply System") was filed by Otis Elevator on Dec 19, 2013. The application was issued on Jan 27, 2021.

Patent Summary

Elevator power supply system with over-voltage protection, comprising a switch mode power supply, a first voltage monitor, a second voltage monitor, a comparator, and a micro control unit. The power supply converts main power to an output voltage, while the first and second monitors continuously measure the output voltage. The comparator and micro control unit compare the output voltage to a reference voltage, triggering a protective shutdown when the output voltage exceeds a predetermined threshold, such as 60V DC.
