This paper proposes the use of H-bridge inverter for feeding a Permanent magnet Synchronous Machine (PMSM) in Electric Vehicle (EV) applications which allows the power transferred from the electrical source to the mechanical load and on the other hand to operate in degraded operating mode even though with one or several phases nonsupplied. In this first an existing method such as three phase in...

A scheme for a three-level voltage space phasor generation with common-mode voltage elimination is proposed. An open-end-winding induction motor, fed from both ends by two threelevel inverters, which are realised by a cascading two two-level inverter, is used in this configuration. The voltage space vectors of individual three-level inverters, which generate the same commonmode voltage in the i...

This Project deals with an Embedded Z-source inverter to control the three phase induction motor. The Z-source inverters are recent topological options for buck–boost energy conversion with a number of possible voltage and current-type circuitries. The common advantage of Z-source inverter and Embedded Z-source inverter is the inclusion of an LC impedance network, placed between the dc input so...

This paper presents a photovoltaic system as a standalone system. The proposed system consists of photovoltaic (PV) module, battery energy storage system (BESS), high frequency transformer, and multilevel inverter (MLI). The MLI consists of two H-bridge single phase inverter per arm (phase) with unequal dc voltages which needs 6 isolated dc sources for the conventional MLI. The relative values ...

This paper presents a hybrid cascaded H-bridge multilevel motor drive Direct Torque Control (DTC) scheme for electric vehicles (EVs) or hybrid EVs. The control method is based on DTC operating principles. The stator voltage vector reference is computed from the stator flux and torque errors imposed by the flux and torque controllers. This voltage reference is then generated using a hybrid casca...

This The Permanent Magnet Synchronous Motors (PMSM) are used for medium power applications and preferred over conventional motors like Induction and Synchronous motors due its superior performance, efficiency and controllability. Normal voltage source inverters are suitable only for three phase drives. Cascaded multi-level inverters are used to improve the power quality. The Hexagram inverter h...

This paper presents a model predictive controlled three-level three-phase active neutral-point-clamped (ANPC) inverter for distributing the voltage stress among the semiconductor power switches as well as balancing the neutralpoint voltage. The model predictive control (MPC) concept uses the discrete variables and effectively operates the ANPC inverter by avoiding any linear controller or modul...

Multilevel inverters, including the flying-capacitor topology require more complex control due to the additional flexibility offered by the multiple output voltage levels. One such control method is based on the conventional sinusoidal pulse width modulation (SPWM) scheme and uses multiple triangular carriers. There are a number of SPWM variants that achieve the desired inverter control. This p...

Inverters used as the interface for a distributed generator in a three-phase four-wire system sometimes operate with a large neutral current because of unbalanced loads and singlephase (possibly nonlinear) loads. Voltage balance within the dc-link of the inverter is important for proper operation of the inverter, and the neutral current is a significant disturbance to this. It is preferable to ...
