A New Space Vector Modulation Scheme for Multilevel Inverters Which Directly Vector Quantize the Reference Space Vector

IEEE Transactions on Industrial Electronics, 2015
A new space-vector-based sigma delta modulation scheme for any general N-level voltage source inverter is proposed in this paper, which directly quantizes the reference space vector. The proposed scheme uses the sigma delta modulation with the quantizer implemented by the proposed space vector quantizer. A new scheme is proposed for directly quantizing

An effective software implementation of the space-vector modulation

IEEE Transactions on Industrial Electronics, 1999
An effective software implementation of the space-vector modulation (SVM) on the rotating - frame is proposed. The conven- tional SVM algorithm requires complex computations, such as square root and arctangent. The SVM algorithm is further developed to deter- mine directly conduction times of switches without requiring complex computations.

Space-Vector-Based Hybrid Pulsewidth Modulation Techniques for Reduced Harmonic Distortion and Switching Loss

IEEE Transactions on Power Electronics, 2010
Novel switching sequences can be employed in spacevector-based pulsewidth modulation (PWM) of voltage source inverters. Differentswitching sequences are evaluated and compared in terms of inverter switching loss.
