This paper presents a nonisolated, high boost ratio hy-brid transformer dc–dc converter with applications for low-voltage renewable energy sources. The proposed converter utilizes a hy-brid transformer to transfer the inductive and capacitive energy simultaneously, achieving a high boost ratio with a smaller sized magnetic component. As a result of incorporating the resonant operation mode into...

This paper presents an interleaved boost converter with coupled inductors for photovoltaic (PV) energy conversion. The proposed soft-switching boost converter uses an interleaved method to increase its power density and coupled-inductor technology to extend its step-up voltage ratio. To reduce switching losses of active switches, the proposed interleaved boost converter incorporates a synchrono...

Z-Source converter or impedance-source converter is a kind of power converters, which has the responsibility to convert the direct current to alternative current. This converter with respect to its circuit diagram acts as a buck-boost converter except it doesn’t use from DC-DC converter bridge. Γ-source inverters are one of the conventional converters based on impedance-sources; which have been...

A regulation of converters connected in parallel is discussed considering their stored energy and passivity characteristics. From the viewpoint of stored energy, a new regulation method to conserve and share the stored energy can be found. The energy stored in inductors and capacitors is transferred to loads so that the load keeps the energy dissipation constant. Though numerical simulation, th...
