This paper introduces a new method to track the saliency of a PMSM motor fed by a four-leg inverter in case of a single phase open circuit fault through measuring the dynamic current response of the motor line currents due the IGBT switching actions. In the case of a single phase open circuit fault, a fault-tolerant control strategy that includes taking appropriate actions to control the two re...

-This paper describes a newly developed triggering circuit, has been use to turn on and off the solidstate switches, such as TRIAC switched capacitors applications. A linear ramp signal based synchronization technique has been propose and implemented successfully, for the capacitor switching operation of a simple power system. This scheme enables the firing circuit to adjust itself against any ...

This paper deals with a reduced switch multi-level inverter for the solar photovoltaic system-based 127-level inverter. The proposed technique uses minimum number of switches to achieve maximum steps in staircase AC output voltage when compared flying capacitor inverter, cascaded type multilevel and diode clamped use decreases cost system.

In this study, a novel topology for symmetrical voltage source multilevel inverter is proposed, which comprises series connection of basic unit cells with H-bridge. It offers same voltage level with lower number of power semiconductor switches as compared with traditional cascaded Hbridge and other recent topologies, thereby reducing the number of gate drivers which in turn reduce the installat...

The four-switch three-phase (FSTP) inverters are known for their cost-effective advantages and minimal switching losses. However, such inverter topology’s progress is lagging due to control constraints requirements, including voltage vector limitations parameter perturbations. To overcome the issue, this paper proposes a triple-voltage-vector model-free predictive current (TVV-MFPCC) FSTP inver...

This paper presents an active solution to a commonmode voltage created by typical three-phase inverters. It is shown that the addition of a fourth leg to the bridge of a threephase inverter eliminates the common-mode voltage to ground created by the modulation of the inverter. An appropriate fourphase LC filter is inserted between the inverter and the load in order to create sinusoidal output l...
