OVER-VOLTAGE AND UNDER-VOLTAGE PROTECTION SYSTEM
First Claim
1. An over-voltage and under-voltage protection system for protecting an electrical device, comprising:
- a comparison device configured for receiving an input voltage associated with a power driving the electrical device, and for comparing the input voltage with a predetermined voltage, outputting an over-voltage signal upon a condition that the input voltage is greater than the predetermined voltage, outputting an under-voltage signal upon a condition that the input voltage is less than the predetermined voltage;
a signal controller configured for receiving and outputting the over-voltage and under-voltage signals; and
a switch controller configured for controlling a switch to turn the electrical device off when the over-voltage or under-voltage signals are received from the signal controller.

Abstract
An over-voltage and under-voltage protection system for protecting an electrical device includes a comparison device, a signal controller, a switch controller, and a switch. The comparison device receives an input voltage and compares the input voltage with a predetermined voltage. If the input voltage is greater than the predetermined voltage, the comparison device outputs an over-voltage signal to the switch controller via the signal controller. If the input voltage is less than the predetermined voltage, the comparison device outputs an under-voltage signal to the switch controller via the signal controller. The switch controller controls the switch to turn the electrical device off when the over-voltage or the under-voltage signals are received from the signal controller.
