Multimodular approach has been used recently in some power electronics equipments to achieve large power rating, better reliability, manufacturability, and maintainability. This paper introduces the development of a practical 100 kVA active filter employing this multiconverter approach and having an additional benefit of improving equivalent switching frequency. The control circuit was implemented...
A novel current detection technique with predictor is presented for generation of a real-time estimate of the fundamental component of the distorted input current to an three-phase diode bridge rectifier with resistance or inductance loads, which is suitable to be compensated with shunt active power filter (SAPF). This allows for accurate calculation of cancellation references for SAPF operating under...
