Title
Research on a SPWM Inverter Power Supply System Based on DSP
Abstract
The composition and control principle of one kind SPWM inverter power supply system based on the DSP chip were introduced. Inverter power supply system which got TMS320LF2407 DSP as control device used single polarity double frequency SPWM by asymmetric regular sampling method. Four switch tubes had realized zero-voltage and zero-current soft switch working state to enhance the circuit efficiency. the instantaneous value feedback double-loop control of voltage and current had been adopted. Voltage regulator used the PI adjustments, the feedback signal of electric current loop was inductive current and it adopted the proportional adjustments, the current loop feedback equals to add the lead compensation network of proportion and differential in the voltage feedback. It enables the system more stable. The experimental results show that the inverter power has good characteristics of dynamic and static.
