Abstract

A power generation controller for a vehicle has a rectifier circuit for rectifying the output current of a polyphase ac generator and a regulator for limiting the voltage to a predetermined value. The operation can be restored from the regulated mode reliably. When the battery voltage VB reaches a regulation voltage Vreg at time t1, the phases are regulated. The W-phase is restored at time t2, and then the V-phase is restored at time t3. When the current IW of the W-phase crosses the zero at time t4, the current IU of the unreported U-phase, which is the phase prior to the W-phase, is referenced. If the current IU is positive, the U-phase is restored.

Afterwards, at moment t3, after the electric current I V zero passage of V phase, the output of V phase comparator 114 is by " 0 " change " 1 ", and thus, " 1 " pulse takes place V phase monostable multivibrator 103.As a result, V phase F/F110 is reset, and its Q output is by " 1 " change " 0 ", and the V-FET of full-wave rectifier 300 becomes OFF.That is, V is mutually also from adjusting recovering state.

Afterwards, at moment t4, after the zero passage, the output of the not gate 118 of W phase is by " 0 " change " 1 " once more for the electric current I W of W phase, and thus, " 1 " pulses take place monostable multivibrator 104, and are input to U and door 119.In addition, at this time point, non-being output as of Q " 1 " of W phase F/F111, this output inputs to U and door 119.In addition, at moment t4, the voltage VU of U phase is than-12.5 height, that is, U phase current IU is for just, and thus, the output of U phase comparator 113 is by " 1 " change " 0 ", and the output of not gate 116 is by " 0 " change " 1 ".

As a result, U all becomes " 1 " with three inputs of door 119, and thus, its output becomes " 1 ".In addition, U phase F/F109 is reset, and Q exports by " 1 " change " 0 ", and the U-FET of full-wave rectifier 300 becomes OFF.That is, U is mutually also from adjusting recovering state.

So, according to present embodiment, the two-phase in the three-phase is behind the adjustment recovering state, a remaining phase, when its back phase zero passage, the phase current of self is positive words, just can be from adjusting recovering state, therefore, no matter when last can not occur mutually all can not be from adjusting the situation of recovering state.

In addition, in the foregoing description, be that example describes the present invention with the three phase alternating current motor, still, the present invention not only is defined in this, and four above mutually alternating current machines can be suitable for too.In addition, in the above-described embodiments, the zero passage of phase current only relates to a direction and detects the explanation of carrying out, and still, on the formation of Figure 10, increases by one group again, just can relate to the twocouese zero passage detection.

The effect of invention

According to the present invention, the two-phase in the three-phase after adjust recovering state, a remaining phase, During its follow-up phase zero passage, phase current is positive, just can be from adjusting recovering state.
