“…In this paper, we propose a technology to reduce the CMV and shaft voltage, which are simple and effective for an inverter to drive a variable speed motor, in consideration of the characteristics of a dual three-phase motor. Recently, due to the increase in the use of dual-three phase systems, many shaft voltage reduction methods for these systems have been presented also [29,30]. Although these methods are effective in the reduction of shaft voltage in dual-three phase systems, similar to the modified PWM techniques mentioned above, additional computation is required and the computational burden is increased.…”

This paper proposes a method of eliminating common-mode voltage (CMV) and shaft voltage in dual three-phase motors using the carrier phase shift of space vector pulse width modulation (SVPWM). SVPWM for the dual three-phase motor is simply implemented using two traditional three-phase SVPWM structures. The representative work of the study is to eliminate the shaft voltage by applying the carrier phase shift method due to the cancellation of CMV. It was verified that the proposed method could reduce the shaft voltage with a simple technique, rather than applying a complex algorithm to reduce it. Also, the motor current and torque behaviors are analyzed to confirm that the proposed method does not affect the motor characteristics. The proposed method has been analyzed based on an equivalent circuit model and it has been verified through the experiment that the shaft voltage is simply eliminated by applying the proposed method.INDEX TERMS Bearing fault, common-mode voltage, dual three-phase motor, pulse width modulation inverter, shaft voltage.

“…In addition, ref. [31] accepted carrier wave phase shift to suppress the CMV, however the dualthree phase winding configuration is not considered and large CMV and shaft voltage remain. This paper proposes SVPWM using carrier wave phase shift to eliminate CMV in dual three-phase motors.…”

“…Taking into account carrier-based PWM methods, as shown in Figure 2b, a PWM technique with three triangular carriers with phase-displacements equal to [φ a , φ b , φ c ] = [0, 120, 240] • was proposed in [33], where these carrier phase-displacement angles are found after an empirical trial and error method. In [34], an adaptive sampling time tri-carrier PWM was also proposed, where an effective CMV reduction is achieved for higher modulation indexes.…”

Electric variable speed drives (VSD) have been replacing mechanic and hydraulic systems in many sectors of industry and transportation because of their better performance and reduced cost. However, the electric systems still face the issue of being considered less reliable than the mechanical ones. For this reason, researchers have been actively investigating effective ways to increase the reliability of such systems. This paper is focused on the analysis of the common-mode voltage (CMV) generated by the operation of the VSDs which directly affects to the lifetime and reliability of the complete system. The method is based on the mathematical description of the harmonic spectrum of the CMV depending on the PWM method implementation. A generalized PWM method where the carriers present a variable phase-displacement is developed. As a result of the presented analysis, the CMV reduction is achieved by applying the PWM method with optimal carrier phase-displacement angles without any external component and/or passive filtering technique. The optimal values of the carrier phase-displacement angles are obtained considering the minimization of the CMV total harmonic distortion. The resulting method is easily implementable on mostly off-the-shelf mid-range micro-controller control platforms. The strategy has been evaluated in a scaled-down experimental setup proving its good performance.
