• IM drive
• limit cycle
• DPWM3
• control of limit cycle

Limit cycle oscillations of rotor speed are substantially caused by inverter's dead time, when an induction motor (IM) drive operates in low frequency condition. In this paper, without any hardware modification, discontinuous PWM (DPWM3) modulate strategy possibly controls the unfavorable rotor speed limit cycle under no load operation condition. Simulated results are presented to demonstrate the effectiveness.
