The presence of an LC input filter in an electrical system often leads to degradation of dynamic performance and instability of the system. This paper addresses the global stability study of an electrical system containing a DC power supply, an LC Filter and a constant power load. This latter is realized by a voltage source inverter-permanent magnet synchronous motor or induction motor. To stabilize...
The presence of an LC input filter in an electrical system often results in degradation of dynamic performance and instability of the system. This paper addresses the global stability study of an electrical system comprised of a DC power supply, an LC filter and an actuator (inverter - permanent magnet synchronous motor or induction motor). Circle criterion is used to study the global stability of...
Two time harmonic methods for computing steady state operation of induction motors are validated by time stepping technique. Saturation and space harmonics are considered and the study is focused on the effect of space harmonics on the torque-speed and current-speed characteristics
