The integration of the DG with the utility distribution network offers a number of technical, environmental and economic benefits. It also gives a great opportunity for distribution utilities to improve the performance of networks by reducing its losses. The technical challenges associated with the DG can be subdivided into three categories: - The system interface to the grid. - Operation and control of the DG. - Planning and design. This work focuses on the first and second categories and aims to investigate a SVPWM algorithm for high power voltage source three level neutral point clamped inverter with operation and control system in sinusoidal mode. This technique provides the nearest switching vectors sequence to the reference vector and calculates the on-state durations of the respective switching state vectors. We used commonly know nearest three vector (NTV) approach. The calculations are only depends on the modulation index and reference vector angle. The work describes systematically the algorithm development, system analysis, DSP based implementation and extensive evaluation study to validate the modulator performance. The interfacing between the grid and DG through SVPWM
