Impact of Mismatch Cables Impedances on Active Motor Terminal Overvoltage Mitigation Using Parallel Voltage Source Inverters

Non-treated transient motor terminal overvoltage due high-speed switching sources and long cable length can be twice the original source voltage amplitude. In some cases, this overvoltage can cause premature motor insulation failure. A topology widely applied in industry is subject of this overvoltage: motors driven by voltage source inverter, connected by long feeding cable. There […]
