Abstract:High power density, high voltage gain soft-switching PWM DC-DC converter with a tapped inductor is proposed in this paper as a front-end for low-voltage sources in energy generation systems. The leakage inductance is incorporated into the resonant tank, decreasing the component count. The use of the boost capacitor connected in series with the secondary windings of the tapped inductor causes high voltage gain at the low turn ratio of the coupled inductor. By incorporating a resonant passive clamp circuit, not … Show more
