Abstract
An isolated resonant conversion control apparatus includes a voltage and current obtaining unit configured to obtain an output voltage and an output current of an output-side switch transistor of an isolated resonant conversion unit, and a processing unit configured to calculate a switching frequency of an input-side switch transistor of the isolated resonant conversion unit based on the output voltage and the output current, obtain a turn-on offset time and a turn-off offset time of the output-side switch transistor relative to the input-side switch transistor based on the switching frequency of the input-side switch transistor, obtain a duty ratio of a second driving signal based on a duty ratio of a first driving signal, the turn-on offset time, and the turn-off offset time, and generate the second driving signal based on the switching frequency and the duty ratio of the second driving signal.
