 This paper presents multilevel inverters as an application for all-electric vehicle (EV) and hybrid-electric vehicle (HEV) motor drives. Diode-clamped inverters and cascaded H-bridge inverters, (1) can generate near-sinusoidal voltages with only fundamental frequency switching; (2) have almost no electromagnetic interference (EMI) and commonmode voltage; and (3) make an EV more accessible/saf...

Abstract—This paper presents bifurcation and chaos in a PWM currentmode H-bridge inverter. This inverter exhibits various interesting bifurcation phenomena. First, we briefly explain the behavior of a PWM currentmode H-bridge inverter from viewpoints of the switched dynamical system. In order to analyze the circuit dynamics we derive a return map exactly. Using this map, the stability of the pe...

Multilevel inverters have become more popular over the years in high power medium voltage applications without the use of a transformer and with promise of less disturbance & reduced harmonic distortion. In this paper, two types of multilevel converter in three phase configuration, cascaded H-Bridge multilevel inverter (CMLI) and diode clamped multilevel inverter (DCMLI) of 5 and 7-level are mo...

In this paper comparison of Selective Harmonic Elimination (SHE) method with different Pulse Width Modulation (PWM) technique which are used as gate pulse for firing the IGBT‟s. Higher order harmonics are easily eliminated by selecting a proper tuned value filters but lower order harmonics such as 3rd, 5th, 7th, and 9th are not easily eliminated. This paper includes NewtonRapson method with ran...

Induction motors are popularly used in various applications because of the proposed modest construction, substantiated process, and limited size specific power. The traditional AC traction drives experimentally analyzed. There is a high circulating current due to Common-Mode Voltage (CMV). Circulating Bearing Current (CBC) major problem conventional two-level voltage source inverter fed paralle...

In this research, a new space vector modulation control algorithm is proposed to increase the reliability of cascaded H-bridge multilevel inverters in case faulty situations, where one or several power cells do not function. Methods detect faults ensure finding open-circuit module exactly, which fast and easy program. By giving detailed analysis impact cells, optimal redundant level states are ...

<span>In this paper, <span>a voltage source inverter is utilized as a distributed static compensator (DSTATCOM). The DSTATCOM used for the elimination of harmonics caused by nonlinear load. reference currents were estimated with synchronous frame (SRF). Conventionally, SRF uses voltage, load current and filter to compute track desired DSTATCOM. sliding mode controller feedback linea...
