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...

A two level fault tolerant voltage sourse inverter(VSI) for permanent magnetic drives is designed and tested. Generally a two level inverter consists of three legs. In this case an extra (redundant ) leg is added that replaces the fault leg. Extra leg is added by using by back to back connected thyristor this inverter works on both open circuit and short circuit fault. The main advantage is pos...

This paper proposes five level diode clamped Z source Inverter. The existing PWM techniques used for ZSI are restricted for two level. The two level Z Source Inverter have high harmonic distortions which effects the performance of the grid connected PV system. To improve the performance of the system the number of voltage levels in the output waveform need to be increased. This paper presents c...

-Because of the acute shortage of conventional energy resources, renewable energy harness is gaining attention. Voltage source inverter forms the interface to feed the power from the renewable source to utility. In order to increase the modularity of the system, the use of several parallel inverters of reduced rating is preferred. An effective control strategy to maintain the amplitude and freq...

Abstract: The simultaneous elimination of common-mode voltage and DC-link capacitor voltage imbalance is achieved in a five-level inverter scheme for an induction motor drive throughout its operating range. A dual five-level inverter-fed open-end-winding induction motor structure is used for the proposed drive. Initially, the operating limitations of achieving this dual task for the fivelevel i...

In the field of electrical solar power conversion efficiency is the most important topic. Also the elimination of high frequency ripple on inputand output side is an increasingly important topic. In common single-phase inverter applications the current of the solar array shows a remarkable ripple due to power pulsation on the grid. This entails two significant disadvantages: Reduced over-all ef...

First, we create a MOS-NDR (negative differential resistance) cell and then put two MOS-NDR cells in cascode (totem-pole) structure. With MOBILE (monostable-bistable transition logic element) theorem we can built a MOS-NDR inverter by placing a NMOS in parallel with the lower part of the cascode structure. The MOS-NDR inverter cascades two Common-Source amplifier and feedback to MOS-NDR inverte...

In the last decades, the applications of power inverter increased rapidly. As a result, in spite of rectifier, an inverter with a high-power electronic oscillator has capability to convert direct current (DC) into alternating current (AC) in different forms. In this paper, a new fuzzy logic control (FLC) is suggested to an improved modeling inverter of a single-phase voltage source using LC fil...
