Abstract

Abstract 

Electrical and electronic devices require protection against voltage drop, overshoot, and fluctuation of the main supply. A microcontroller-based circuit was designed where the main voltage connected to the board feeding the controlled devices was monitored by this circuit and ensure the voltage is measured within a required voltage range (RVR). The circuit was kept monitoring the power supply and ensures the main voltage connected to the board feeding the controlled devices connected if it measures within a required voltage range (RVR). If the voltage falls below or above the RVR then the main supply would be disconnected from the feeding board. The circuit then will keep monitoring the voltage and reconnect it to the feeding board once its amplitude falls back stable in the required voltage range. This design was simulated successfully using Proteus software.
