Design And Construction A 2Kva Automatic Voltage Regulator Using Microcontroller And Display
Pages: 72 | Words: 8267 | Chapters: 1-5 | Type: Project
Abstract
Voltage regulators play a crucial role in maintaining the stability of appliances in various settings, including homes, offices, and industries. However, mains supply often experiences significant voltage drops due to distribution line losses. To address this, a voltage regulator ensures that the output voltage to appliances remains at a nominal 220V, despite input voltage fluctuations. This project presents an automatic voltage regulator with adaptable power ratings, leveraging the intelligence of the PIC16F877A microcontroller. This low-cost, widely available microcontroller enables the circuit to maintain a stable 220V output, even when input mains voltage varies between 90V and 240V. The regulator responds swiftly, producing a smooth output within 100ms of input voltage changes, outperforming servo stabilizers which take seconds to adjust. Although programming the PIC16F877A microcontroller can be challenging due to its RISC architecture and limited instructions, supportive development tools are available to facilitate the process.
