The commutation of the inverter switches can produce an alternating common mode voltage in the panel poles, which may induce a capacitive leakage current [13,14], as shown in Fig. 1(a) and (b). Sign in to download full-size image Fig. 1. (a) Common mode current and parasitic capacita...
Common-mode voltages (CMVs) can lead to premature failure of the motor insulation system in medium-voltage (MV) current source inverter (CSI)-fed drives. A series of nonzero-state modulation (NZSM) techniques are proposed for the CMV reduction. In these methods, the zero states are avoided...
This paper presents the implementation of the modulation strategy to balance the neutral point potential (NPP) in three level NPC inverters. This method employs the space vector pulse width modulation technique which gives the strong regulating ability of common mode voltage of DC link capacitors. ...
Common mode (CM) choke saturation is a practical problem in common-mode filter applications. It's generally believed that the leakage inductance of common-mode chokes makes the core saturated. This paper analyzes two new mechanisms for common-mode choke saturation due to common-mode voltage, and...
