A novel over-current protection methodology applied for flyback converters is proposed, with advantages of getting immune to input voltage variation and inductance deviation from production-line manufacturing and thus accurate over-current-protection (OCP) is available. Experimental results guarantee highly significant improvement based on OCP variation less than 0.733% under universal line voltage conditions. Moreover, additional components are unnecessary in a real board, bringing no burden in circuit design. The aforementioned advantages of the target features have been analyzed in detail through conscientious simulations and the feasibilities are verified depending on prototypical circuits.
