Abstract
Voltage stabilizers are used for many appliances in homes, offices and industries. The mains supply suffers from large voltage drops due to losses on the distribution lines en route. A voltage stabilizer maintains the voltage to the appliance at the nominal value of around 220 volts even if the input main fluctuates over a wide range. In this work, an automatic voltage stabilizer can be adapted to any power rating. Its intelligence lies in the program on PIC 16F873A—a low-cost microcontroller that is readily available. The circuit, when used with any appliance, will maintain the voltage at around 220V even if the input mains voltage varies between 90V and 240V. The PIC16F877A is an RISC (reduced instruction set computer) microcontroller with 35 instructions, and hence program development with it is rather tough. But, there are good support programs. ...
