In many developing modern technologies demand for Fuzzy Logic controlled applications has increased. In various
cases, the mathematical model of the control process is very difficult to implement with respect to computer processing power
and memory and a system based on factual rules may be morel adequate. Furthermore, fuzzy logic is perfectly suited to low cost
implementations based on less-resolution A/D converters, cheap sensors and 4-bit or 8-bit one-chip microcontroller chips. To
enhance performance or add new attributes, new rules can be easily added in such type of systems. The performance of Fuzzy
Logic Controllers is well implemented in the field of control theory because it provides robustness to dynamic system parameter
variations as well as improved transient and steady state performances. In this work an attempt has been made to minimize the
effect of disturbed supply on rectifier and to achieve low input current THD with reduced ripple DC output voltage using a
fuzzy logic controller.
