Abstract:
A resonant converter includes a first switch on a primary side and a second switch coupled to the first switch, a first synchronous rectification switch on a secondary side conducted according to a switching operation of the first switch, a second synchronous rectification switch on the secondary side conducted according to a switching operation of the second switch, and a switch control circuit configured to detect a waveform of one end voltage of at least one of the first synchronous rectification switch and the second synchronous rectification switch, determine one of a below region and an above region, and differently control conduction duration of the first and second synchronous rectification switches according to a determined result.

Claim (Index 15):
The converter of  claim 1 , wherein the switch control circuit comprises:\n an SR on-time determiner configured to detect an end voltage of the first synchronous rectification switch and an end voltage of the second synchronous rectification switch, detect a first conduction duration of the first synchronous rectification switch and a second conduction duration of the second synchronous rectification switch in an immediately preceding switching cycle, and set an on-time of each of the first and second synchronous rectification switches in a next switching cycle based on a duration obtained as a result of subtracting a dead time between the first and second synchronous rectification switches from the detected first and second conduction durations; and\n an SR on-time compensator configured to calculate a first extended duration by subtracting a first duration of the first synchronous rectification switch and the second dead time from a duration spanning from a turn-on time of the first switch to a conduction end time of the first synchronous rectification switch, and calculate a second extended duration in the immediately preceding switching cycle by subtracting a first duration of the second synchronous rectification switch and the dead time from a duration spanning from a turn-on time of the second switch to a conduction end time of the second synchronous rectification switch.
