4 Frequently Asked Questions about "Six-leg inverter voltage vector"

What is a five-phase six-leg inverter?

In order to validate the proposed modulation, a five-phase six-leg inverter was built; its main components are shown in Figure 13. The DC voltage source is an AMREL SPS600-10-K0E3 and is regulated to 110 V. The five-phase six-leg inverter is composed of two three-phase two-level VSIs.

Is there a three-dimensional space-vector for a five-phase six-leg converter?

Likewise, the only three-dimensional space-vector (3D SV-PWM) for a five-phase six-leg converter is proposed in [ 28 ]. To fill this gap in the literature, this work proposes a three-dimensional RCMV-PWM (3D RCMV-PWM), based on the well known NS-PWM, to be applied in five-phase six-leg motor drive systems.

How many VSIs are in a 5 phase inverter?

The five-phase six-leg inverter is composed of two three-phase two-level VSIs. Each converter includes an SK15GDT4ET IGBT module, an SKHI71 driver and a DC bus capacitor of 2 mF per converter. Finally, the power inverter is switched at 16 kHz ( = s) and feeds an RL load of 10 and 10 mH per phase.

Can high-frequency PWM cause inverter bearing damage?

Generating sinewaves using high-frequency PWM can lead to bearing damage caused by common-mode voltage (CMV) from the inverter. Specifically, the unbalanced phase voltages produced by the PWM algorithm driving the power devices result in CMV profiles with abrupt edges.
