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

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 pulse width modulation (SVPWM) is widely used. The complexity is due to the difficulty in determining the location of the reference vector, the calculation of ...

Analysis of a Novel Dead-time Compensation Technique for Three Phase Space-vector Pwm Based Vsi Drives

Due to the finite turn on and turn off times of switching devices typically a dead-time is inserted in between the off going and turning on devices to prevent a shoot through in the DC link. Even though this assures safe operation several undesired attributes such as fundamental voltage drops, output waveform distortions & torque pulsations are also introduced as a result of this time delay. Th...

A Space Vector Modulation Based Three-level PWM Rectifier under Simple Sliding Mode Control Strategy

In this paper, a voltage oriented control strategy for three-level PWM rectifier based on Sliding Mode Control (SMC) is introduced in order to obtain fast and accurate response of dc-bus voltage. To verify the validity of the analysis and the feasibility of the proposed control method a set of simulation tests have been conducted using Matlab/Simulink. The simulation results show that compared ...
