Abstract: A flyback converter with improved performance is discussed. The flyback converter has a control and drive circuit, which drives the primary power switch with a weak drive if the time interval between two adjacent turn-ons of the primary power switch is longer than the reference time length; and drives the primary power switch with a strong drive if the time interval between two adjacent turn-ons of the primary power switch is shorter than the reference time length.

Abstract: A flyback converter with improved performance is discussed. The flyback converter may be nor may not be under a burst mode; or may exit from the burst mode. When the flyback converter is under a normal operation mode, the secondary power switch is turned on after the primary power switch is turned off, until an OFF condition of is met; and the secondary power switch is turned on again for an additional time before the primary power switch is turned on at a next switching cycle. When the flyback converter enters the burst mode and then exits from the burst mode, the secondary power switch is not turned on again for the additional time before a primary power switch's turn-on at the next switching cycle.
