Abstract:
A resonant power converter and a frequency tracking method for a resonant power converter are disclosed to determine a resonant status of the resonant power converter by sampling a secondary current, thereby controlling frequency of a drive signal. Therefore, the frequency of the drive signal tracks resonant frequency of the resonant power converter. The resonant power converter includes an inverter branch, which connected to the inverter branch, a transformer connected to the resonant branch, and a rectification and filtering branch connected to the transformer. A primary side of the transformer is connected to the resonant branch, and a secondary side of the transformer is connected to the rectification and filtering branch. A detection branch is connected to both the secondary side of the transformer and the rectification and filtering branch.

Claim (Index 9):
The frequency tracking method according to  claim 6 , wherein the generating the first information according to the pulse signal corresponding to the secondary current and the drive signal comprises:\n determining that a rising edge of the pulse signal corresponding to the secondary current and a rising edge of the drive signal are synchronous; determining that a falling edge of the pulse signal corresponding to the secondary current lags behind a falling edge of the drive signal; and generating the first information, wherein the first information is used to indicate that the resonant power converter works in a first area; wherein the controlling the frequency of the drive signal according to the first information comprises decreasing the frequency of the drive signal according to the first information.
