LLC converter synchronous FET controller and method of operation thereof
摘要:
A method for operating a power controller is provided. The method includes activating a rectifying FET upon a detection of an activation body diode conduction current occurring in the rectifying FET. The method generates an activation signal for a corresponding primary FET. The method further includes deactivating the corresponding rectifying FET upon a reception of a deactivation signal. The method further includes then deactivating the corresponding primary FET after delaying the deactivation signal, wherein the delay lessens a conduction time of a deactivation body current of the corresponding rectifying FET. The method further includes generating a deactivation signal and deactivating the corresponding rectifying FET upon a reception of the deactivation signal and deactivating the primary FET after delaying the deactivation signal. The delaying lessens a conduction time of a deactivation body current of the corresponding rectifying FET.
