摘要

A novel Overcurrent (OC) protection methodology applied for flyback converters is proposed. This technique provides the advantage of immunity to input-voltage variation and inductance deviation from production-line manufacturing, making accurate OC available. Experimental results guarantee highly significant improvement based on OC variation of less than 0.733% under universal-line voltage conditions. Moreover, additional components are unnecessary in a real board, so no burden is placed on circuit design. The advantages of the target features have been analyzed in detail through conscientious simulations, and the feasibilities were verified on prototypical circuits.
