Characteristics of Two-Phase Inverter-Fed Three-Phase Induction Motor Drive

In recent years, advances in power electronics have led to an increase of three-phase motor drive systems controlled by inverters. If inverters fail operate, there is the possibility a shutdown drives. specific applications such as electric vehicles, inverter failure leads loss vehicle’s propulsion ability, causing safety issues like traffic accidents and other consequences. order assure non-stop operation, emergency strategies for are necessary. Less costly two-phase more frequently used support conventional Recent research into drives utilizing developed advanced techniques with different control methods. This paper compares performances inverter-fed induction using V/f three indirect vector methods performed same experimental apparatus. The experiment evaluated based on torque-speed characteristics efficiency. Among evaluated, results identified flux weakening best that also has widest area terms
