In this paper, an optimal converter drive method for Permanent Magnet Synchronous Motor (PMSM) with a 3-level inverter is discussed in terms of loss minimization. The 3-level inverter can change an operation mode between two modulations namely, PWM and 1'pulse modulation at a decided point. In this paper, we discuss the interchange point for the two modulations subject to the total loss of PMSM drive system in regards to the motor speed. First, the analysis on intersection point between PWM and 1'pulse modulation is demonstrated, and then the results show, that the motor drive system achieves the highest efficiency with PWM before the intersection point. On one hand, implementation of 1'pulse modulation can achieve the highest efficiency.

“…A multi-purpose optimization PWM scheme was introduced for 5L-ANPC inverters [10], which is a proper candidate for high power motor drive applications due to its high efficiency, structure, controllability, and performance [11]. This method can balance the NPP and limit the switching frequency of high-voltage rated IGBTs, and also reduce the CMV.…”

In this paper, a novel space vector pulse width modulation (SVPWM) scheme for reducing the commonmode voltage (CMV) in the three-phase five-level active neutral-point clamped (5L-ANPC) inverter for the machine drive systems is proposed, where only the 55 selected voltage vectors with low values of CMV instead of all 125 voltage vectors are utilized. This PWM scheme can significantly reduce the common-mode voltage without the increase of switching loss and total harmonic distortion (THD) of the output voltages compared with the conventional one. With the 55 voltage vectors only, the inverter can still work in the full range of modulation index (MI). In addition, the DClink capacitor and flying capacitor voltages can also be controlled for balancing. The PSIM simulation results show that the peak value of the CMV is decreased to one twelfth of the DC-link voltage.Index Terms-Active neutral point clamped inverter, common-mode voltage, multilevel inverter, space vector pulse width modulation.
