Boost PFC converter versus bridgeless boost PFC converter EMI analysis
2014 International Conference on Applied and Theoretical Electricity (ICATE), 2014The main drawback related to the PFC converters is the increasing of the electromagnetic interference (EMI). Thus, the high frequency noise must be filter out in order to ensure compliance with EMI European standards (EN 1000-3-2 or EN 1000-3-4). The paper investigates two topologies: the conventional boost PFC converter and the bridgeless boost PFC ...

A novel voltage-bucking/boosting converter: KY buck-boost converter
2008 IEEE International Conference on Industrial Technology, 2008In this paper, a novel voltage-bucking/boosting converter, named as KY buck-boost converter (i.e. 2D converter) is presented herein. Unlike the traditional buck-boost converter, this converter possesses fast transient responses, similar to the behavior of the buck converter with synchronous rectification.

Design and comparison of quadratic boost and double cascade boost converters with boost converter
2017 14th International Multi-Conference on Systems, Signals & Devices (SSD), 2017Basically, the output voltage in renewable energy sources is improved using the boost converter, which is the key part in a photovoltaic chain. In this converter, the switching frequency is limited; hence the output voltage is reduced. To overcome this problem, two topologies are proposed; the quadratic boost converter results by combining the ...

Multilevel boost DC-DC converter derived from basic double-boost converter
2013 15th European Conference on Power Electronics and Applications (EPE), 2013This paper presents a nonisolated multilevel step-up dc-dc converter suitable for high power and high output voltage application. The main features of proposed converter are: reduced voltage across the semiconductors; low switching losses; and reduced volume of input inductor. This paper focuses on the five-level structure of the proposed converter, in

2011 IEEE Ninth International Conference on Power Electronics and Drive Systems, 2011
In this paper, a high-voltage boost converter is presented, whose operating principle is based on charge pumps and series boost converters. Furthermore, although three switches are used, no isolated gate driver is needed instead of one half-bridge gate driver and one low-side gate driver.

Modeling and Comparison of Boost Converter With Cascaded Boost Converters
2018Photovoltaic (PV) energy is a very important renewable energy source. The output voltage in renewable energy sources a is improved using DC-DC converters, which are the key part in a photovoltaic chain. Among the classic DC-DC topologies, the boost converter is the most used because of its simplicity and high efficiency.

Flying-capacitor boost converter
2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012This paper introduces the flying-capacitor dc-dc boost converter. In the proposed topology, a high voltage gain ratio and improved conversion efficiency are achieved with low inductor core and copper losses. The input current ripple of the new converter is low while its ripple frequency is high, yielding a low-sized input filter.
