-The simulation of a nonlinear controller with power sharing control capabilities for a wind energy system double input buck boost–buck boost converter is presented. A multiple-input DC–DC converter is useful to obtain the regulated output voltage from input power source such as a wind array. Double input DC-DC buck boost converter principle of operation and the equations describing the convert...

This paper presents a detailed small-signal and transient analysis of a full bridge PWM DC-DC converter designed for high voltage, high power applications using an average model. The derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. Results obtained in the analysis of the high voltage and high power design examp...

In this paper, a MSEBC (modified-SEPIC embedded-boost converter) is proposed, which can deal with either utility power or PV (photovoltaic) power to serve as HB-LED (High-Brightness Light-EmittingDiode) driver and battery charger. While connected to utility, the proposed converter can perform PFC (power factor corrector) for universal line input. Once power failure occurs, it can draw energy fr...

A novel integrated buck-flyback non isolated power factor (PF) correction (PFC) converter is proposed in this paper. This new converter is an inherent integration of a buck converter and a flyback converter, which operates in either flyback mode or buck mode according to whether the input voltage is lower or higher than the output voltage. In this way, the dead zones of ac input current in trad...

A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

Cross regulation is the main technical drawback of a Single-Inductor Multiple-Output (SIMO) dc-dc converter. This paper proposes a multivariable digital controller to suppress the cross regulation of a SingleInductor Dual-Output (SIDO) buck converter in Continuous Conduction Mode (CCM) operation. The controller design methodology originates from the open-loop shaping of the Multi-Input Multi-Ou...

A power factor correction (PFC) converter with interleaved multi-channel topology is gaining increasing attention due to its ability in reducing input and output current ripples, but an Electromagnetic Interference (EMI) noise filter is still required for suppressing the large high-frequency switching noise that could potentially degrade the input power quality of the supplying grid and cause m...

The generalised steady-state analysis of the multi-phase interleaved boost converter with coupled inductors operated in continuous inductor current mode is addressed. The analytical expressions for efficiency, inductor and input currents, and output voltage are derived from the transformed average state–space model. Generalised expressions for the input and inductor current ripples and the outp...
