  • Abstract
    Recently, most electronics manufactures require high reliability of switched mode power supply against various fault situations such as over load, output short or rectifier diode short. This paper presents simple and effective protection schemes for the off-line flyback converter. The proposed protection schemes can protect the power MOSFET from various abnormal conditions. The validity and effectiveness of the proposed schemes are verified through experimental results.
