This paper analyzes the advantages and limitations of using the floating(or flying-) capacitor technique as a building block with differential input and either differential or single-ended output to implement voltage amplifiers, multiplexers, and coherent amplitude demodulators. Theoretical analysis, supported by experimental results, shows that the fully differential configuration has a better...

In this study, the authors propose a non-isolated high step-up interleaved DC/DC converter that can be applied to sustainable energy system. The proposed achieves voltage gain by applying coupled inductor and switched capacitor method based on an boost converter. two inductors connected in parallel with input side have distinct structure. Specifically, single has primary secondary series output...

This paper explores Switched Inductor (SL) Quasi Z-source Inverter which has high boost factor and performance when compared to other Z-Source inverters along with three control methods: simple boost, maximum boost and maximum constant boost. The proposed inverter improves the input current, reduces the passive count and also the reliability. The simulations are done in MATLAB/Simulink environm...

Electrical Engineering (ABSTRACT) The conventional power factor correction circuit has a fixed output voltage. However, in some applications, a PFC circuit with a wide output voltage range is needed. A single phase power factor correction circuit with wide output voltage range is developed in this work. After a comparison of two main power stage candidates (Buck+Boost and Sepic) in terms of eff...

This paper presents an interleaved resonant converter to reduce the voltage stress of power MOSFETs and achieve high circuit efficiency. Two half-bridge converters are connected in series at high voltage side to limit MOSFETs at Vin/2 voltage stress. Flying capacitor is used between two series half-bridge converters to balance two input capacitor voltages in each switching cycle. Variable switc...

(ABSTRACT) A single-phase grid connected transformerless photovoltaic (PV) inverter for residential application is presented. The inverter is derived from a boost cascaded with buck converter along with a line frequency unfolding circuit. Due to its novel operating modes, high efficiency can be achieved because there is only one switch operating at high frequency at a time, and the converter al...

This paper explains about basic working principles, implementation problems, and experimental results of a new power factor correction (PFC) topology. In this proposed topology, a totem-pole boost PFC circuit that works under interleaved critical-conduction-mode (CRM) condition is presented. The circuit is developed towards high efficiency, high performance, lowcost, simple control scheme, and ...
