A Space Vector PWM Scheme for Multilevel Inverters Based on Two-Level Space Vector PWM

IEEE Transactions on Industrial Electronics, 2006
Multilevel inverters are increasingly being used in high-power medium voltage applications due to their superior performance compared to two-level inverters. Among various modulation techniques for a multilevel inverter, the space vector pulsewidth modulation (SVPWM) is widely used.

A space vector PWM algorithm for a hybrid multilevel inverter

12th IEEE International Power Electronics Congress, 2010
The implementation of a Space Vector PWM (SVPWM) algorithm to generate the switching scheme for a multilevel hybrid inverter is presented in this paper. Unlike other multilevel inverters, a minimum number of switching devices, a split DC link, and a 50% rated, three-phase transformer are combined to generate seven-level SVPWM output voltage waveforms ...

Performance Analysis of Vector controlled PMSM Drive modulated with Sinusoidal PWM and Space Vector PWM

2020 IEEE International Power and Renewable Energy Conference, 2020
Permanent Magnet Synchronous Motors (PMSM) are considered as energy efficient motors suitable for modern applications like electric vehicles. Field oriented control or vector control is a superior control strategy for PMSM drives. It is known that in vector control, decoupled control of torque and flux is obtained as in the case of a DC motor.

A novel overmodulation technique for space vector PWM inverters

PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 1998
In this paper, a novel overmodulation technique for space-vector pulsewidth modulation (PWM) inverters is proposed. The overmodulation range is divided into two modes depending on the modulation index (MI). In mode I, the reference angles are derived from the Fourier series expansion of the reference voltage which corresponds to the MI. In mode II, the
