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...

KHAN, MOHAMMAD SAMEER. Analysis of Flyback-PV Inverter to Enable Low Voltage Ride-Through (LVRT) Operation During Grid Fault. (Under the direction of Dr. Subhashish Bhattacharya). Flyback based PV micro-inverter is a very popular low-cost solution for integrating the photovoltaic (PV) module to an AC grid. As the penetration level of these inverters in the grid is increasing, it may cause probl...

Abstract: Voltage source inverters (VSIs) have been widely utilized in electric drives and distributed generations (DGs), where electromagnetic torque, currents and voltages are usually the control objectives. The inverter flux, defined as the integral of the inverter voltage, however, is seldom studied. Although a conventional flux control approach has been developed, it presents major drawbac...

This paper describes the investigation of the grid-connected three-phase inverter for photovoltaic (PV) application. The inverter control system modeling is carried out in MATLAB/SIMULINK environment. With the aids of the proportional-integral controllers, sinusoidal pulse-width modulation (SPWM) control technique and Park transformation, the inverter control system managed to convert PV power ...
