Quadratic‐boost‐double‐flyback converter [PDF]
Combining low‐voltage power sources with loads that require high‐voltage levels is a challenge, especially for power devices above 500 W. In this context, this study presents a new dc–dc high‐gain converter using coupled inductors. The new converter uses only one switch and output capacitors with low values.
