-As the use of power electronic equipment is spreading, the degradation of the power quality in the utility networks is increasing and is becoming a major problem. Limiting the current distortion is therefore a concern for both utilities and consumer. Power converters such as rectifiers, power supplies and at a higher power level, arc furnaces are the sources of harmonics. This harmonics can be...

Chapter 3 presents ANN based adaptive shunt passive filter, whose performance is found to be superior to fixed element shunt passive filter in harmonic and reactive compensation. However, the drawback is that it can provide only partial harmonic and reactive power compensation. Hence, an ANN based digital controller for active filter is developed. It compensates for the major portion of source ...
