摘要：

This paper presents a novel single stage push-pull boost converter with a improved integrated magnetics and ripple-free input current. It is found that the push pull converter when the duty cycles greater than 50% can simplify the front of boost-type converter to a novel single stage converter. Coupled inductor techniques provide a method to reduce the converter size and weight and achieve ripple-free current. All the magnetic components including input filter inductor and step-down transformer are integrated into a single El core. The prototype is built to demonstrate the theoretical prediction.
