Design of the Inversion Power-Supply Control System Based on DSP

摘要：

This paper presents the inversion power-supply control system with the software of dual SPWM modulation system and voltage closed loop PI control strategy and the hardware foundation of DSP TMS320LF2407A. Aiming at the requirements of rapidity of system, it adopts the feedforward and amplitude control strategy on aspect of control strategy to reduce the dynamic response error. Aiming at the requirements of stability and stationarity, it takes the segmentation intelligent PI control strategy. In order to avoid the system oscillation caused by the input direct current voltage fluctuation, it designs the voltage sluggish loop in the software. It has significant effects in improving the inversion wave form, anti-interference and anti-bias magnet, ensuring the stability of system, reducing the harmonic wave and undesired sound, and improving the wave form quality and the adaptation to load, etc.
