Single-Stage transformerless AC/DC converter received much attention in the universal line application. Unlike the existing converters a new high step-down transformerless single-stage single-switch AC/DC converter is proposed. The topology integrates a buck-buck-boost converter with low intermediate bus and output voltage. The converter utilizes a buck converter as a PFC cell and buck-boost co...

Fuel cells are new alternative energy resource that has a great promise for distributed generation and electric vehicle application. However, fuel cells have a slow response due to their slow internal electromechanical and thermodynamic response. To optimize the fuel cell system performance, a fuel cell DC-DC converter with an appropriate controller which can regulate the power flow and automat...

This paper a novel yet simple zero-voltage switching (ZVS) interleaved boost power factor correction (PFC )DC/DC converter used to charge the traction battery of an electric vehicle from the utility systems. The proposed topology consists of a passive auxiliary circuit, placed between two phases of the interleaved front-end boost DC-DC converter, provides enough current to charge and discharge ...

This paper introduces a novel Bi-directional DC-DC converter with artificial neural network controller (ANN).Bidirectional power flow is obtained by the same power components and provides a simple, efficient, and galvanically isolated converter. In the presence of DC mains the converter operates as buck converter and charges the battery. When the DC main fails, the converter operates as boost c...

This paper presents a high step-down tranformerless single-stage single-switch ac/dc converter suitable for universal line applications (90–270 Vrms ). The topology integrates a buck-type power-factor correction (PFC) cell with a buck–boost dc/dc cell and part of the input power is coupled to the output directly after the first power processing. With this direct power transfer feature and shari...

The multi-input dc/dc boost converter is proposed in this paper. The proposed converter uses two sources such as wind, photovoltaic(PV) and battery as a storage element for hybridizing alternative energy sources. This converter draws the power from two different sources depending upon climatic condition and deliver it to the dc load individually or simultaneously. The system is applicable for D...

Portable electronic devices not only require switching DC-DC converters to be compact and integrated but also compliant to wide off-chip LC filter variations, which are subject to manufacturing tolerances, temporal and thermal parameter drifts, and more often than not, application-driven constraints. While optimal LC compliance has been demonstrated in ΣΔ buck converters, little has been done i...
