An improved three-level inverter SVPWM control method

The three-level inverter Space Vector Pulse Width Modulation (SVPWM) method is researched, in accordance with the calculation of the vector variation a triangle rotational relations is proposed, which can make the time calculation and time state allocation modules be simplified and improved. Compared with the traditional SVPWM control method, its control becomes more simple and easy to implement. The simulation results show the effectiveness of the method.
