–Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. This investigation is to identify a low cost, small size, efficient and reliable ac to dc converter to meet the input performance index of UPS. The per...

––The objective of this paper is to propose anovel multi-input power converter for the gridconnected hybrid renewable energy system in order to simplify the power system and reduce the cost. The proposed multiinput power converter consists of a Cuk fused multi-input dc–dc converter and a fullbridge dc– ac inverter. The incremental conductance method is mainly used to accomplish the maximum powe...

Classic high-frequency transformers enable for isolated DC/DC converters to achieve high input voltage gain by the turns ratio. Through the use of an isolation transformer made in planar technology with interleaved windings leakage inductance can be significantly reduced and voltage overshoots can be marginalized. By applying balancing transformer with integrated input inductor in the setup of ...

DC-DC converters are widely used in Industrial, Commercial and Non Renewable energy applications and also especially in Switch Mode Power Supplies. The two phase interleaved DC-DC boost converter (IBC) for low input voltage applications is designed and implemented with digital controller. The interleaved concept is used to meet the increased demands and also a low current ripple in source curre...

Half-bridge inverter is very suitable for singlephase on-line UPS applications because it offers very desirable features. These include fewer active switches, a common neutral connection – not requiring an isolation transformer, and sinusoidal input currents if a power factor correction (PFC) converter is used at the front end. This paper presents a comparative study of PFC converters for singl...

A new single-stage single-switch input-currentshaping (S4ICS) technique, which combines the boost-like input-current shaper with a continuous-conduction-mode (CCM) dc/dc output stage, is described. In this technique, the boost inductor can operate in both the discontinuous conduction mode (DCM) and CCM. Due to the ability to keep a relatively low voltage (<450 Vdc) on the energy-storage capacit...

This work presents the experimental validation of a 40 kW electric vehicle (EV) charger. The proposed system comprises two 20 modules connected in parallel at input and output. Each module has stages—as grid converter Vienna Rectifier (VR) was chosen, as an isolated DC/DC stage, Series-Resonant Dual-Active-Bridges (SRDABs) input-series-output-parallel (ISOP) configurations were applied. AC/DC s...
