    A conventional forward converter requires a transformer having an extra winding to assist in magnetic core reset, thus complicating the design and increasing the production cost. These shortcomings can be overcome by using an RCD clamp forward converter. This article presents a simplified analysis and design of the RCD clamp forward converter. The laboratory prototype is constructed. Experimental results demonstrates that the prototype converter is capable of providing a constant output voltage throughout its operating condition and has the maximum efficiency of 85%.

    This paper presents performance comparison between a two-switch and RCD clamp forward converters. The performance comparison is carried out through experimentation on the two prototype circuits, which have the same circuit specifications and similar component values. Aspects to be compared include voltage stress of switching components, output voltage regulation, transient response due to a step-load, and efficiency. Test results show that, while the two converters exhibit equal performance on output voltage regulation, the two-switch forward converter has a lower voltage stress on power switching devices, faster transient response, and higher efficiency than the RCD clamp forward converter.
