Abstract

The conventional high frequency signal injection method is to superimpose a high frequency voltage signal to the commanded stator voltage before space vector modulation.
Therefore, the magnitude of the voltage used for machine torque production is limited. In this paper, a new high frequency injection method, in which high frequency signal is
generated by shifting the duty cycle between two neighboring switching periods, is proposed. This method allows injecting a high frequency signal at half of the switching frequency without the necessity to sacrifice the machine fundamental voltage amplitude. This may be utilized to develop new position estimation algorithm without involving the inductance in the medium to high speed range. As an application example, a developed inductance independent position estimation algorithm using the proposed high
frequency injection method is applied to drive a synchronous reluctance machine. Simulation and experimental results are given to support the proposed new approach.
