摘要
A feedback method and apparatus for cancellation of magnetizing inductance current are presented. A voltage driver applies a voltage signal to a primary of a transformer. Feedback apparatus detect changes in the voltage driver output current that are attributable to magnetizing inductance current. Changes in output current are used to obtain a current error, which is integrated to control a current ramp generator. The output of the current ramp generator is applied to the transformer primary as a compensating current for canceling the magnetizing inductance current.
