Abstract
Controller and method for a power converter. For example, a controller for a power converter includes: a mode detector configured to determine a mode of operation for the power converter; a first gate driver configured to output a first drive voltage to a first transistor related to a first auxiliary winding coupled to a primary winding, a secondary winding, and a second auxiliary winding; a second gate driver configured to output a second drive voltage to a second transistor related to the primary winding; wherein the first gate driver is further configured to, if the mode of operation satisfies one or more first predetermined conditions, generate the first drive voltage so that the first transistor remains turned off during a switching cycle of the power converter.
