Manufacturing Voltage Stabilizers with Digital Control Using Atmega 8535: A Comprehensive Study

Introduction

Voltage fluctuations are a common problem in electricity sources, which can damage electronic equipment and lead to costly repairs. In this study, we designed a voltage stabilizer with digital control using an ATMEGA 8535 microcontroller to overcome this problem. This tool is an efficient solution that can maintain a stable voltage level, extending the life of electronic devices and reducing maintenance costs.

Design and Components

The voltage stabilizer consists of several main components, including a microcontroller circuit that functions to process input and output, the power supply circuit to provide a voltage source to the microcontroller, the LCD screen for the information display, and the L293D IC that functions as a motor driver. The voltage sensor circuit becomes a crucial component in this system, which is tasked with providing feedback to the control system when the output voltage of the Toroid transformer does not reach 220V.

How it Works

When the sensor detects instability in the output voltage, the microcontroller processes the data and sends commands to the motor driver to turn the lever connected to the transformer. This process continues until the resulting voltage is stable again at the desired value. The system is also equipped with a safety mechanism that automatically disconnects the load if the voltage output exceeds the threshold limit of 230V, protecting electronic equipment from damage due to excessive voltage.

Microcontroller Selection

The Microcontroller of the Atmega 8535 was chosen for this application due to its ability to process data quickly and the availability of input and output pins sufficient to connect various components. Additionally, ease of programming and flexibility in controlling control logic make it the ideal choice for this application.

Power Supply Design

The special designed power supply series is also very important, as it is the main source of voltage for the whole system. The stability of this power supply will directly affect the performance of the tool. Therefore, special attention must be given in the design of the power supply so that it can function properly in various load conditions.

Voltage Sensor

The voltage sensor used in this system functions as the main supervisor. By using a high-quality sensor, the accuracy of voltage measurement can be maintained, so that the response to changes in voltage can be done quickly. This ensures that the stabilizer can function optimally and maintain voltage at a safe level for connected electronic devices.

Implementation and Benefits

Through the implementation of this system, it is expected to make a significant contribution in maintaining the stability of the voltage, which in turn will extend the life of electronic devices and reduce maintenance costs due to damage. This stabilizer is very suitable for use in various environments, ranging from households to industry, where stability of voltage is the key to operational success.
