This paper proposes an isolated three-phase rectifier power-factor correction using two single-phase buck preregulators in continuous conduction mode. The use of the Scott transformer renders a simple and robust rectifier to operate with unity power factor. With only two active switches, the rectifie...
The rectifier can operate in an advanced working condition, a lag working condition, a unit power number working condition or the like. The large-power mixed cascade bridge type unity power factor rectifier has the advantages of the simplified topological structure of the main power circuit, ...
AC/ DC ( alternating current/ direct current) voltage source pulse width modulation ( PWM) rectifier is proposed, which realizes a sinusoidal AC input current and unity power factor.为了实现交流输入和整功率因数，提出了一种基于自适应B样条（BS）神经网络的三相PWM整流器控制策略；
It is shown that for Q>2/ pi the rectifier operates in continuous conduction mode and the output voltage is independent of the load. Also, it is shown that for Q>2 the line current is nearly sinusoidal with less than 5% third-harmonic distortion and the power factor is essentially unity....
