2023 AHR EXPO INNOVATION AWARDS VENTIL ATION WINNER SMAR TD TECHNOLOGIES SMARTD CLEAN POWER VFD (Booth C5948) INNOVATION: SmartD's Clean Power Variable Frequency Drive changes the motor control landscape. By delivering a clean, sinusoidal signal, it reduces motor system losses by up to 40% and extends motor lifetime in a compact footprint that can be deployed without ancillary fi lters. The SmartD VFD integrates widebandgap (WBG) semiconductors into its multilevel inverter architecture and combines them with patented modulation algorithms to produce a pure-sine wave electrical signal without the need for external fi lters. WBG semiconductors have intrinsic characteristics that make them more effi cient: on-state losses are 10% to 80% lower and switching losses are 9 to 30 times lower than standard IGBTs. While the benefi ts of WBG are clear, they are but a piece of the SmartD innovation equation. By combining a single-carrier harmonicscanceling modulation with a multilevel architecture and the high-frequency switching of the WBG transistors, SmartD is able to integrate fi lters 400 times smaller than auxiliary fi lters normally required to achieve a comparable signal quality. The integrated miniature-fi lters reduce the overall footprint and simplify wiring. They also reduce fi lter losses while improving motor effi ciency, resulting in an overall system effi ciency improvement and system-loss reduction of up to 40%.
