Zusammenfassung:The paper presents the design and performance evaluation of two-stage AC power adapters for notebook computers which deliver 70 W from the universal line. Three versions of the flyback power converter, as well as the PWM and resonant half-bridge power converter were evaluated and compared with respect to their efficiency, component stress, output filter size and complexity.
