| 8. | Active pfc techniques have been researched systematically and used widely in the recent twenty years because of high power factor ( pf ) and low total harmonic distortion ( thd )
有源pfc技术具有功率因数高和总谐波含量小等优点,在过去的二十年里,得到了长足的发展和广泛应用。 |
| 9. | It is an effective method to overcome the periodic disturbance . in ac power system , nonlinear loads are major sources of total harmonic distortion ( thd ) . this built the motivation for this dissertation
为了解决逆变电源系统中非线性负载引起的波形畸变问题，本文对基于重复控制理论的逆变电源控制技术进行了深入的研究。 |
| 10. | The detecting method of dvr is different from harmonic and reactive current detecting methods . it need detect not only total harmonic distortion but also the difference between fundamental wave component and reference value
Dvr的检测方法与谐波、无功电流的检测不同，不但需要检测出除基波分量之外的总畸变分量，还要检测出基波分量与基波基准值之差。 |
