Research on Control Strategies of an Open-End Winding Permanent Magnet Synchronous Driving Motor (OW-PMSM)-Equipped Dual Inverter with a Switchable Winding Mode for Electric Vehicles
An open-end winding permanent magnet synchronous motor (PMSM) has a larger range of speed regulation than normal PMSM with the same DC voltage, and the control method is more flexible. It can also manage energy distribution between two power sources without a DC/DC converter. This paper aims at an electric vehicle equipped with OW-PMSM drive system with dual power sources and dual inverters; ba...
متن کاملCirculating Common-mode Current Reduction in Open- End Winding Induction Motor
PWM Inverters in induction motor drives are known to cause common-mode voltage which results in leakage current flowing through the parasitic capacitors to the ground and creates drawbacks such as shaft voltage, bearing current, electromagnetic interference problems. CMV elimination using conventional Three-level NPC multilevel topology has certain drawbacks. An improved SVPWM strategy using Du...
متن کاملDual two-level inverter scheme for an open-end winding induction motor drive with a single DC power supply and improved DC bus utilisation - Electric Power Applications, IEE Proceedings-
A dual two-level inverter fed open-end winding induction motor drive with a single DCpower supply is proposed. The proposed scheme produces voltage space vector locations identical to those of a conventional three-level inverter. In the conventional neutral-clamped three-level inverter, the series-connected DC link capacitors carry the load current, resulting in a fluctuating neutral point. Als...
متن کاملAn Optimal Control Strategy for DC Bus Voltage Regulation in Photovoltaic System with Battery Energy Storage
This paper presents an evaluation of an optimal DC bus voltage regulation strategy for grid-connected photovoltaic (PV) system with battery energy storage (BES). The BES is connected to the PV system DC bus using a DC/DC buck-boost converter. The converter facilitates the BES power charge/discharge to compensate for the DC bus voltage deviation during severe disturbance conditions. In this way,...
متن کاملA Novel PWM Inverter Switching Strategy for a Dual Two - level Inverter Fed Open - end Winding Induction Motor Drive
Absrracl--A dual two-level inverter fed open-end winding induction motor drive is proposed in this paper. A total of 64 voltage space phasor combinations are possible in this scheme as each inverter produces eight voltage space phasors. The proposed scheme produces voltage space phasor locations similar to that of a 3-level inverter. In a 3-level Inverter the series connected DC link capacitors...
