数字控制的逆变电源及其控制方法
摘要：
本发明公开了一种数字控制的逆变电源及其控制方法。增广状态反馈数字控制器输出端与逆变器输入端相接，逆变器输出端与电压传感器输入端及负载相接，电压传感器第一输出端与减法器负输入端相接，减法器正输入端接收参考量ur，减法器输出端与控制器输入端相接，逆变器接直流电源，逆变器中引出的电流与电流传感器的输入端相接，电流传感器输出端和电压传感器第二输出端分别与控制器负输入端相接。减法器和控制器构成微处理器。该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。
摘要（英）：

This invention discloses a digit controlled inversion supply and its control method, in which, the output of an augmented state feedback digit controller is connected with the input of an inverter, the output of which is connected with the input of a voltage sensor and a load, the first output end of the voltage sensor is connected with the negative input of a subtracter, the positive input of which receives reference volume ur, the output of which is connected with the input of a controller, the inverter is connected DC supply, the current led out from the inverter is connected with the input of the current sensor, the output of which and a second output of the voltage sensor are connected with the negative input of the controller constituting a microprocessor with the subtracter.
