Abstract

An isolated power converter includes primary side switch devices coupled to secondary side rectifying devices by a transformer and a controller. Responsive to a transient load condition, the controller switches the primary side switch devices at an initial switching period having a positive half cycle and a negative half cycle to transfer energy across the transformer during the positive half cycle and the negative half cycle. The positive half cycle and the negative half cycle of the initial switching period have the same initial duration. The controller is further operable to symmetrically reduce the duration of the positive half cycle and the negative half cycle for at least one subsequent switching period during the transient load condition.
