Bidirectional Power Flow

Nowadays, the matrix converter (MC) has become the prominent power converter. Its unique qualities like single-stage ac to ac conversion, bidirectional power flow, sinusoidal response, unity power factor, and no need for dc-link makes it superior among all power converters. This archival literature investigates the various pulse width modulation (PWM) methods and proposed a novel pulse width modulation (PWM) method named Time Equivalent space vector pulse width modulation. In this article this novel modulation method is compared with exiting carrier-based pulse width control and space vector control methods for a 3 phase to 3 phase matrix converters. Simulation model is built in Matlab and comparative analysis based on total harmonic distortion (THD) will be given for different methods. Simulation results revealed that total harmonic distortion (THD) of Time Equivalent space vector PWM is least so this novel method is best and more efficient in comparison to others.

Increasing Demand

To generate the required reference vector than triangle comparison based PWM techniques for three-level inverters the space vector based PWM (SVPWM) strategies contain broader choice of switching sequences. This space vector based PWM technique involves in various steps. These steps are computationally exhaustive. The SVPWM has been used in three phase inverter control system. The center-aligned PWM is the most effective way for the Microprocessor Control Unit implementation of the SVPWM, because it can easily generate the center aligned PWM of the multilevel inverters for generation of the signal of space vector pulse width modulation (SVPWM), this concept brings out the method. The inverter leg switching times are generated by this algorithm and middle vector switching times are centered in a sampled interval. The proposed algorithm does not require any sector identification. And it reduces the computational time as a result. The adjacent voltage space vectors are forming the small triangles it is called sectors. Multilevel converters can meet the increasing demand of power ratings and power quality associated with reduced harmonic distortion and lower electromagnetic interference. Furthermore to optimize switching waveforms, space vector pulse-width modulation algorithms offer great flexibility among them. Finally the results are verified through MATLAB/SIMULINK

This paper elucidates a comparative analysis of hysteresis current control space vector modulation (HCC-SVM) and 3-dimensional space vector modulation (3D-SVM) for control of 3-level neutral point clamped (NPC) inverter. The NPC inverter topology is much suitable for single input applications and medium and high power applications. The detailed comparative analysis of total harmonic distortion (THD) for both modulation control strategies is analyzed. Among various modulation strategies, these two control strategies increased more attention due to the improved output compared to the other conventional methods. The simulation and hardware results are evident that 3D-SVM is the most efficient controller for capacitor balancing, common mode voltage minimization, THD minimization and attain low voltage stress across switch, but in terms of system design and complexity in switching time calculation is simple in the HCC-SVM method. The simulation and hardware results are verified using simulink and FPGA processor, respectively.
