【Abstract】 The operation of traditional SVPWM control strategy is complex,in view of this situation,a new control strategy based on four quadrant converter platform is introduced,which does not need coordinate transformation,trigonometric function calculation and sector judgment any more.Through the establishment of mathematical model and simulation analysis,a small platform of 6kW three-phase converter is built.By conducting experiments it is concluded that the experimental results are in good agreement with the theoretical analysis and also show the feasibility and effectiveness of this algorithm.Such related ideas can be extended to multilevel inverter model,and then applied to the field of electric vehicles and new energy power generation.更多还原
