Embodiment
Three, be example with maximum output inductance current 6kV/100A, illustrate its implementation (U1=6kV, U2=500V)
1, embodiment 1 employing is saved harmonic wave and is suppressed loop example 1. with the inductance current generator of 3 branch roads
Fig. 2 is the specific implementation principle of inductance current generator 2 among the present invention, form by N group controlled inductance load branch, each group controlled inductance load branch is by reactor Xm (m=1,2 ... .N) and gate-controlled switch Km (m=1,2, .N) constitute, each branch road reactor Xm (m=1,2 ... .N) numerical value can or take other to distribute pattern by geometric ratio, equivalent distribution.Gate-controlled switch Km can be made of controllable silicon SCR, IGBT, GTO, IGCT or vacuum switch etc.For each branch road, when the conducting state that changes the switch that reactor was connected in series, just can change the electric current output of this branch road, as adopt controlled electronic power switch, then this branch current can be 0 to u1/Xm (m=1,2 ... .n) any quick adjustment between, because every branch current is quick adjustment continuously all, thus total current I1=(I ' 1+I ' 2+ ... + I ' n) just can realize according to the conducting state of inductance current of required transformer by suitable each switch of control.General control mode can be according to the complete turning part of required primary current switch, and keeps one of them to be in conducting angle scalable state, can reduce the harmonic content of primary circuit like this.More simply be: when transformer among Fig. 11 adopts high short-circuit impedance transformer (as impedance voltage near 100%), then the way among Fig. 2 can be reduced to 1 branch road, and can save reactor and directly gate-controlled switch is linked to winding head (a1, x1), control loop is just comparatively simple like this.
