TO Convert Based on DC–DC Based on 3SSC and VMC
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 12
Abstract
Proposed on this work as a viable solution to step-up a low battery voltage into a high voltage dc link. This converter is suitable for non-isolated on-line UPS systems with common neutral connection that improves bypass circuit installation. Furthermore, smaller size, higher efficiency, and increased reliability are features that spread the transformer less products. This paper introduces a new family of dc–dc converters based on the three-state switching cell and voltage multiplier cells. A brief literature review is presented to demonstrate some advantages and inherent limitations of several topologies that are typically used in voltage step-up applications. The adopted control strategy uses a hybrid control that implements both analog and digital controllers, that implements the average current mode control. It presents characteristic of continuous input current through the batteries that improve its lifetime, the maximum voltage across the controlled switches is equal to one fourth of the total output voltage, and voltage equalization across the dc-link capacitors is intrinsic. In order to verify the feasibility of this topology, principle of operation, theoretical analysis, and experimental waveforms are shown for a 1.55 kW assembled prototype. proposed on this work as a viable solution to step-up a low battery voltage into a high voltage dc link.

The analyzed converter can be applied in uninterruptible power supplies, fuel cell systems, and is also adequate to operate as a high-gain boost stage with cascaded inverters in renewable energy systems. Furthermore, it is suitable in cases where dc voltage step-up is demanded, such as electrical fork-lift, audio amplifiers, and many other applications.
