ABSTRACT:
The present invention provides a voltage transformer circuit which combines half-bridge topology with a current-mode control according to the present invention. The DC--DC converter circuit according to the present invention includes: a power transformer, where the primary side of the transformer includes a power winding and a balance winding and a means for injecting a correction current proportional to the amount of current flowing in the balance winding, where the means for injecting a correction current proportionate to the amount of current flowing in the balance winding including a means for sensing the amount of current in the balance winding. The correction current is injected in such a way so that current from the means for injecting a correction current is subtracted from the switch current lengthening the on-time of the switches in the half-bridge circuit thereby driving the bridge center tap back towards V.sub.in /2, preventing an unstable or runaway operating condition.
