Mitigation of Non-Eliminated Harmonics of Three-Level Multipulse Three- Phase Active Front End Converters with Low Switching Frequency
نویسندگان
چکیده
A Three-Level 12 pulse Three-Phase Active Front End ensures reduced low order harmonics influence and therefore minimizes volume and amount of network side filters. This paper presents the experimental study concerning the regenerative unity-power factor operation of a 3LAFE converter, highlighting the possible reduction of non-eliminated harmonics by the introduction of slight variations of modulation index and DC-Link voltage regarding a selective harmonic distortion factor (SHD). This work opens new possibilities for avoiding or reducing harmonic filters, especially by operating within weak networks and stringent conditions to be studied in further projects

متن کاملA New Analog-based LO Harmonic Rejection Technique with Tunable Notch Frequency
An effective technique for mixer LO harmonic rejection in a SAW-less wideband receiver front-end is proposed. The proposed technique provides a tunable notch that can be placed at any frequency like mixer LO harmonics, to avoid the aliasing in baseband after mixing. An analog LC notch is used in a cascode transconductor, and it can reject one of the 3rd or 5th harmonics. T...
