Abstract: Pole-phase modulation (PPM) winding layout plays a pivotal role in achieving pole-changing operation of induction motors. Several PPM pole-changing approaches have been demonstrated to ...

Abstract: Dual-port dc-ac converters utilizing the Neutral-Point-Clamped (NPC) multilevel topology are increasingly considered for the compact integration of multiple sources and loads in various ...

Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...
