A New Simplified Space–Vector PWM Method for Three-Level Inverters


I. INTRODUCTION
RECENTLY, with the dramatic improvements in high
voltage technologies, high voltage insulated gate bipolar
transistor (HVIGBT) and gate commutated thyristor (GCT) are
expanding the area of their application. For the high performance
ac drive systems at increased power level, high quality
inverter output with low harmonic loss and torque pulsation
is necessary. In case of the conventional ....etc

DIRECT TORQUE CONTROL FOR MATRIX CONVERTER-FED THREE PHASE INDUCTION MOTOR WITH HYBRID PSO
ABSTRACT
Direct Torque Control (DTC) for Induction Motors using Matrix Converters is a high performance motor
control scheme with fast torque and flux responses. This paper presents a new control scheme based on
hybrid particle swarm optimization (HPSO). The main advantages of the matrix converter are combines
with those of the DTC technique, generating the required voltage vectors under 0.9 input power factor
operations. The results ....etc

ABSTRACT

In this paper a new single phase to three-phase converter for ac motor is proposed. The proposed converter employs only six switches and incorporates active input current haping feature, which results in sinusoidal input current at close to unity power factor. The front-end rectifier in the proposed converter permits bidirectional power flow and therefore provides for excellent regulation against fluctuations in source voltage. This feature also facilitates regenerative braking of ac motor drive. An easy to implement control stra ....etc

CAPACITOR VOLAGE BALANCING OF A SPACE VECTOR MODULATION BASED ON THREE LEVEL INVERTER
Features of Multilevel inverter-
1- Multilevel inverter can eliminate need for step up
transformer.
2- Reduce harmonics produced by the inverter
3- Output voltage and power increase with number
of levels.
4- Harmonic content decreases as number of levels
increases and filtering requirements are reduced.
5- In absence of any PWM techniques , ....etc

Abstruct-
Analysis, design, and implementation of the space vector modulated three-phase to three-phase matrix converter with input power factor correction are presented. The majority of published research results on the matrix converter control is given an overview, and the one, which employs sheous output-voltage and input-current space vector modulation, is systematically reviewed. The modulation algorithm is theoretically derived from the desired average transfer functions, using the indirect transfer function approach. ....etc
