“…Thus, several sensor-less control techniques for enhancing the performance of these drives like Back-EMF zero-crossing detection, Varying inductance approach, Flux-linkage variation, MRAS control, Extended Kalman Filter method etc. have been described in [2,[4][5][6][7][8][9]. Compared to multi-stage drives, an Integrated Buck-boost Buck converter is a single-stage converter employing a single switch, which offers advantages like reduced switching losses, improved dynamic performance, power factor correction, improved power quality, fast voltage regulation, and Zero-Current switching(ZCS) at Turn-ON for reduced losses at the switch [1].The PFC converters generally have two operational modes: (i) Continuous Conduction Mode (CCM) (ii) Discontinuous Conduction Mode (DCM).…”
