Abstract: Methods for flyback converters are provided. The method, adopted by a flyback converter circuit including a transformer, including: determining an output voltage output from a secondary circuit of the transformer; feeding a feedback voltage based on the output voltage from the secondary circuit back to a primary circuit of the transformer; increasing a current limit and a switching frequency of a primary current with the feedback voltage; and supplying the primary current to a primary winding of the transformer.

Abstract: A power monitor includes a detecting circuit, a processing circuit, and a warning circuit. The detecting circuit detects a first abnormal condition of a primary side circuit and a second abnormal condition of a secondary side circuit. The processing circuit calculates a first class and a first occurring number of the first abnormal condition, and calculates a second class and a second occurring number of the second abnormal condition. The processing circuit determines whether the first occurring number is larger than a first predetermined number corresponding to the first class; if it is, the processing circuit outputs a first abnormal signal. The processing circuit determines whether the second occurring number is larger than a second predetermined number corresponding to the second class; if it is, the processing circuit outputs a second abnormal signal. The warning circuit outputs a warning signal according to the first or the second abnormal signal.
