Abstract

This paper proposes an integration control algorithm with DPTC-SVM for a Dual-PWM Converter to optimize the parameters of the rectifier and inverter. The control algorithm utilizes direct power control for the PWM rectifier and direct torque control for the PWM inverter. Compared with the traditional DPTC control algorithm and DPTC-SVM algorithm, the stability of the system was analyzed by adding power feed forward loop. The rapid dynamic response and anti-interference ability are improved with the proposed algorithm, though the capability of the DC-link capacitor decreases. With TMS320LF2407 DSP platform to carry out physical verification of the induction motor current, torque and flux characteristics. Simulation and experimental demonstrations are presented to show that the input-output power matches well and the algorithm fullfill the unity power factor conditions.
