数字控制的逆变电源的控制方法
摘要：
本发明公开了一种数字控制的逆变电源的控制方法。该方法实时采集逆变电源的输出电压和输出电流，利用采集的输出电压和负载电流预测逆变电源的电压和电流状态变量，根据预测的输出电压的误差信号和预测的电流信号进行控制信号的运算，将由此得到的控制信号用于逆变电源的控制，此控制方法可以消除开关管导通时间损失，负载适应性强，鲁棒性大为增强，并可利用快速灵活的运算提高数字控制性能，使控制效果接近模拟控制。利用该方法制备的逆变电源动态响应快速、平稳，非线性负载情况下输出电压总谐波畸变率低，本发明广泛应用在交流稳定电源、不间断电源、柔性交流输电系统、有源电力滤波器、超导磁储能系统、可再生能源供电系统中。
