Space Vector Based Hybrid PWM Techniques for Reduced Current Ripple
TL;DR: This paper brings out a method for designing hybrid PWM techniques involving multiple sequences to reduce line current ripple, and identifies all possible sequences, which result in the same average switching frequency as conventional space vector PWM (CSVPWM) at a given sampling frequency.
Journal ArticleDOI
Space-Vector-Based Hybrid Pulsewidth Modulation Techniques for Reduced Harmonic Distortion and Switching Loss
TL;DR: In this article, a hybrid space vector-based hybrid PWM technique is proposed, which reduces the inverter switching loss compared to conventional space vector PWM (CSVPWM) and discontinuous PWM techniques at a given average switching frequency.
Journal ArticleDOI
Modified SVPWM Algorithm for Three Level VSI With Synchronized and Symmetrical Waveforms
TL;DR: The objective of the present work is to improve the output waveform of three level inverters used in high-power applications, where the switching frequency is very low, by maintaining the synchronization, half-wave symmetry, quarter- wave symmetry, and three-phase symmetry in the pulsewidth modulation (PWM) waveforms.
Journal ArticleDOI
Advanced bus-clamping PWM techniques based on space vector approach
TL;DR: In this paper, a double-switching clamping sequence was proposed to reduce the harmonic distortion in the line currents over CSVPWM and existing bus-clamping PWM.
Journal ArticleDOI
Analytical evaluation of harmonic distortion in PWM AC drives using the notion of stator flux ripple
G. Narayanan,V.T. Ranganathan +1 more
TL;DR: In this paper, the authors presented a method to evaluate harmonic distortion due to space vector-based pulsewidth modulation (PWM) strategies for ac drives, which is general enough to deal with division of zero vector time as well as division of active vector time within a subcycle.
