This paper analyzes the impact of converter design elements on the operating performance of DC/DC converters, used worldwide for renewable energy sources. The design of inductor and capacitor elements is made considering the acceptable output ripple of voltage and current. This paper presents the methodology for determining the inductances and capacitances required for DC/DC converter operation within...
Wave energy converters generally suffer from a low operating power factor due to the nature of the long wavelength water wave and the inductance of the electrical generator employed in the conversion process. A Forced Commutated Series Capacitor (FCSC) converter can be connected between the generator and the load circuit to prevent power factor degradation. This paper describes the effectiveness of...
This paper presents a power converter for grid connection of renewable energy sources, consisting of a ZETA converter associated with a bridge inverter operating at low frequency. The Zeta converter, operating in the discontinuous conduction mode (DCM), produces a rectified sinusoidal current waveform synchronized with the electric grid. The full-bridge inverter, connected to the output of the Zeta...
This paper presents the study and development of a processing power system to be used in the grid connection of renewable energy sources to the power grid. The system consists of a Zeta converter associated with a full bridge inverter operating at low frequency. The Zeta converter, operating in discontinuous conduction mode (DCM), plays the main role in this arrangement, producing a rectified sinusoidal...
