Abstract :
In this paper, fuzzy control theory is applied for the realization of an AC line voltage regulator (AVR). In general, the conventional approach uses a complex and expensive analog control circuit to achieve the control requirements of AVR. In order to reduce the cost and to improve the output characteristics of AVR, a microprocessor with fuzzy control is applied to obtain low cost and superior performance. The operating principle of the AVR topology mentioned above and its new control strategy are illustrated. Finally, the experimental results of the proposed 300 VA AVR prototype are described and discussed
