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

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

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

HARMONIC ANALYSIS OF SEPARATELY EXCITED DC MOTOR DRIVES FED BY SINGLE PHASE CONTROLLED RECTIFIER AND PWM RECTIFIER
ABSTRACT
PWM rectifier is an ac to dc power converter which is implemented using power electronic semiconductor switches such as MOSFET, IGBT. Different from diode bridge rectifiers, PWM rectifiers achieve bidirectional power flows,which can be extensively used in battery charger, UPS system, regulated dc voltage source. SCR converters provide low power fac ....etc

CHAIN DRIVES IN LOW TORQUE DRIVES AND REDUCING PULSATIONS
INTRODUCTION TO DRIVES

Mechanical components used for power transmission.It may be belt, chain or gear depending on engine design parameters like - Distance between crankshaft and camshaft, engine maximum speed, engine-torque and engine construction cost.- Power transmission is done from one shaft to another shaft which may or may not rotate at same spe ....etc

2.1 INTRODUCTION
Direct-current motors are extensively used in variable-speed drives and positioncontrol
systems where good dynamic response and steady-state performance are
required. Examples are in robotic drives, printers, machine tools, process rolling mills,
paper and textile industries, and many others. Control of a dc motor, especially of the
separately excited type, is very straightforward, mainly because of the incorporation of
the commutator within the motor. The commutator brush allows the motor-devel ....etc
