Abstract

In an open-loop V/f controlled high-power low-voltage induction motor drive, sub-harmonic oscillations are commonly observed, especially at light-load and low-frequency operation, because of the dead-time which is introduced to avoid shoot-through in the dc-bus of the inverter. In this paper, such oscillations due to dead-time have been studied and substantially reduced by using a simple and effective dead-time compensation method. A two-step soft-starting method has also been proposed to achieve a fast acceleration of high-power motors without exceeding the current protection limit of the inverter. Experiments have been performed on a 355 kW squirrel cage induction motor drive supplied by a 500 kVA Si-IGBT based voltage source inverter. The steady-state and dynamic performances of the drive with these methods have been successfully verified by apposite experimental results.
