CONTROL APPARATUS OF POWER CONVERTER CIRCUIT
First Claim
1. A control apparatus applied to a power conversion circuit which includes a transformer and a switch circuit including one switch or a plurality of switches, the control apparatus comprising:
- an output voltage detector detecting a value of an output voltage of the power conversion circuit;
an exciting current peak time generator detecting a peak time of an exciting current of the transformer; and
a timing generator generating a switching timing of the one switch or the plurality of switches,wherein the timing generator generates the switching timing of the one switch or the plurality of switches on the basis of the output voltage and the peak time.

Abstract
To detect a peak time of an exciting current of a transformer, a primary current corresponding to the peak time, or a variation time of the primary voltage, and to switch a switch after expiration of a predetermined period from the peak time, after the peak time occurs. A control apparatus 1 is applied to a power conversion circuit 2 which includes a switch circuit 23 including one switch or a plurality of switches and a transformer 21. The control apparatus includes: an output voltage detector 11 detecting a value of an output voltage of the power conversion circuit; an exciting current peak time generator 12 detecting a peak time of an exciting current of the transformer; a timing generator 13 generating a switching timing of the one switch or the plurality of switches. The timing generator 13 generates the switching timing of the one switch or the plurality of switches on the basis of the output voltage and the peak time.
