In this work neural and neuro-fuzzy controllers are developed for the inverters of Uninterruptible Power Supplies (UPS) to improve their transient response and adaptability to various loads. Idealized load-currentfeedback controller is built to obtain example patterns for training the networks. Example patterns under various loading conditions are used in the off-line training of the selected n...

Uninterruptible Power Supplies (UPS) are finding increased applications with the advent of sophisticated electronic equipment. Low power equipment like FAX machines, Personal Computers, etc., form the major portion of the applications. There is a need for cost-effective, light and sleek UPS in the low power range. In low power UPS, the presence of line frequency magnetic components makes the sy...
