The tracking performance of direct power control for dual PWM converter is poor, and the response speed of voltage out loop. The causes of existing conventional direct power control of the problem is analyzed in this paper. According to the influence of the change of active power and reactive power, a switching vector table model in which there are two voltage vectors in some sectors is used. In order to improve the response, the power strategy of feedforward control is put forward based on the power balance relationship. The power of motor side is feedforward on the network side to ensure the given power adding feedforward channel. In the waveform of the power, sudden load response speed, grid current, harmonics, the contrast experiment was done between this control and direct power. The experimental results show that, this improved direct power control strategy for the dual PWM converter can respond quickly to load changes and restore homeostasis, which is robust to load and system parameters perturbation, those verify the effectiveness of the proposed method.
