摘　　要：介绍了基于高性能DSP的逆变电源全数字化控制方案,该方案结合了重复控制、预测PID控制和前馈控制的优点,能减小逆变电源在非线性周期负载下的输出电压谐波畸变率和阶跃负载时的超调量。通过对1.6kVA单相SPWM逆变电源实验装置的实验,实验结果显示所采用的全数字化控制方案能达到逆变电源在各种负载条件下的动态和稳态指标要求。This paper presents a full digital control scheme for inverter power supply based on high-performance DSP. The controller inherits the merits of repetitive controller, predictive PID controller and feedforward control and can minimize the harmonic distortions of output voltage resulted form nonlinear cyclic loads and overshooting under step loads. Experimental results for a single-phase SPWM inverter demonstrate the good performance of the adopted control scheme under all types of loads.
