Harmonic analysis of space vector modulated PWM waveforms

IEE Proceedings B Electric Power Applications, 1990
While most traditional PWM inverters use the asymmetrical regularly sampled triangulation technique to generate waveforms, a recently reported space vector PWM method is rapidly gaining favour in the industrial drives arena as an alternative technique. The paper presents an analysis of the space vector PWM waveform to obtain its spectrum.

Dynamic voltage restorer based on voltage space vector PWM control

APEC 2001. Sixteenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.01CH37181), 2001
A dynamic voltage restorer (DVR) based on the voltage-space-vector pulsewidth-modulation algorithm is presented. Phase-jump compensation is achieved using a software phase-locked loop and a lead-acid battery energy store. A battery-charging control technique using the DVR itself is also described.

Decentralized Space Vector PWM Method for Multilevel Multiphase Converters

2020 2nd Global Power, Energy and Communication Conference (GPECOM), 2020
In this paper, the decentralized modulation for the control of multilevel multiphase converters (MMC) using space vector pulse-width modulation (SVPWM) is proposed. With the proposed method, local information obtained from neighboring cells and by itself is employed so that the cell can adjust the vector and the switching time of the vector itself ...

FPGA realization of space-vector PWM control IC for three-phase PWM inverters

IEEE Transactions on Power Electronics, 1997
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 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.
