摘　　要：介绍了一种基于DSP控制的单相逆变电源设计方案,该方案采用SPWM调制方式。根据逆变电源的特性,采用逆变器直流侧电压作前馈补偿器,使调制深度保持在合适的值,从而使输出经LC低通滤波器滤波后,得到质量较高的正弦波电压。实验证明,该方案效果良好,成本低廉,运算简单,性能稳定可靠,具有良好的实用价值。This paper presents a design for single-phase inverter power supply based on DSP.On the basis of the nature of the SPWM inverter,the DC link voltage is designed to be the feed forward compensator.As the forward back control loop made the modulation index being appropriate,the AC output through LC low-pass filter has a high quality. It is proved that the design has the characters of top performance, stable reliable, lower cost and efficient calculation.These characters makes the design being useful.
