In this paper, we propose and discuss two new control methods for three phase shunt APFs: the sinusoidal line current control method and the instantaneous reactive power compensation control method.

Dead-time effects can be regarded as a kind of space-vector, which is determined by two factors: sector number and direction of phase current.

死区效应可被视为一种空间矢量，它由两个因素决定：扇区数和相电流方向。

But the project's current phase also includes replacement of five two-track bridges, which required reducing the number of active tracks from four to two.
