This paper presents simplified space vector pulse width modulation (SVPWM) based vector controlled induction motor drive. The conventional SVPWM algorithm constructs the required voltage vector in the average sense by using active and zero voltage vectors. Moreover, complexity involved in conventional SVPWM algorithm is more. Whereas, the proposed SVPWM algorithm calculates the switching times ...

This paper presents a new circuit realization of the space-vector pulse-width modulation (SVPWM) strategy. An SVPWM control integrated circuit (IC) has been developed using the state-of-the-art field-programmable gate array (FPGA) technology. The proposed SVPWM control scheme can be realized using only a single FPGA (XC4010) from Xilinx, Inc. The output fundamental frequency can be adjusted fro...

Abstract The modulation of a voltage source inverter output causes losses and harmonic distortions on the load side DC-link capacitor due to discrete switching semiconductors. High-frequent pulses are digitally programmed control determine distortions. This paper presents an optimization in terms pulse- frequency-pattern selection for reducing while keeping minimal. In detail, fact that pulse f...

In recent years, multiphase PWMs have been proposed because of their increased efficiency, reduced torque pulsation, improved fault tolerance, and lower power handling requirement by adopting multiphase machines. In the digital implementation, multiphase reference voltages are sampled and fed into the digital modulator to produce gating signals at a constant clock rate f. This means a finite pu...

The most popular and best modulation method used among Pulse Width Modulation (PWM) technique is Space Vector Modulation (SVM) method. SVM generates low Total Harmonic Distortion (THD) and it is well suitable for motor control. Harmonics is one of the major power quality issues occurring in most of the application. SVM holds the major advantage that only one switch is turned on at a time. The p...

Pulse width modulation strategies have been developed for indirect matrix converters (IMCs) in order to improve their performance. In indirect matrix converters, the LC input filter is used to remove input current harmonics and electromagnetic interference problems. Unfortunately, due to the existence of the input filter, the input power factor is diminished, especially during operation at low ...

Abstract This paper proposes a voltage and frequency controller for a wind turbine-driven independent asynchronous generator. The proposed controller consists of IGBT (Insulated Gate Bipolar Transistor) based three phase voltage source converter along with battery energy storage system at its DC bus and it inherently adapts to the changes in the rotor speed while maintaining a near constant vol...

This paper presents a methodology to apply a novel space vector pulse width modulation control for three phase Z-source inverter. The space vector modulation for the conventional voltage source inverter is modified so that the additional shoot-through states are inserted within the zero states. So zero voltage time period is diminished for generating a shoot-through time, and active states are ...

Abstract: The conventional pulse-width modulation rectifier has the low power factor and more sensors to detect the voltage and current of alternating current side. The traditional direct power control method possesses the defect of unfixed switching frequency. A new method based on three-phase voltage source pulse-width modulation rectifier with high power factor based on direct power control ...
