| 摘 要： | 针对采用AC/DC/AC结构的400 Hz中频电源,整流的非线性形成的谐波电流对电网造成污染,同时使功率因数降低的问题,提出了在输入端采用有源功率因数校正电路,减少谐波提高功率因数;针对当逆变电源输出带非线性负载、死区等,引起输出电压波形畸变和有效值反馈等实时性差的问题,采用了双环反馈,即电容电流内环电压瞬时值外环的控制策略;利用瞬时无功理论abc/dq0对电流、电压进行检测以提高检测的实时性;利用不对称规则采样法产生SPWM。

| Abstract: | The rectified non-linear harmonic current have brought pollution to power grid and reduced the power-factor when adopted the 400Hz intermediate frequency power supply of AC/DC/AC structural.So the active power-factor correction circuit at input terminal was proposed to reduce the harmonic wave and improve power factor.In this thesis,the double-loop feedback,namely a control strategy about the capacitive current inner ring and voltage instantaneous value outer ring,is used to solve the problem of real-time p... |
