Non-isolated high-step-up resonant DC/DC converter
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016A non-isolated high-step-up resonant DC/DC converter made up of a resonant inverter and a passive switched-capacitor (SC) rectifier, is proposed in this paper. The proposed converter is free of transformer and coupled-inductor. Thus, issues related to the leakage inductance and the large volume magnetic component caused by large turn's ratio of high ...

Fault diagnosis in non-isolated bidirectional half-bridge DC-DC converters
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014A new fault diagnostic method is presented in this paper for bidirectional half-bridge DC-DC converters. This algorithm uses only the converter control variables without requiring extra-sensors and its implementation requires only a minimum computational effort. Simulation results in a wind power system including supercapacitors and batteries have been

A Study of Non-Isolated DC–DC Converters for Photovoltaic Systems
International Journal on Energy Conversion (IRECON), 2013As the output power of photovoltaic (PV) system and the switching mode of the converters have a non-linear characteristic, it is important to operate the system at its maximum power point (MPP). The main part of maximum power point tracking (MPPT) controller is the DC-DC tracker converter since it can influence the system performance, and extract the ...

A non‐isolated quasi‐Z‐source‐based high‐gain DC–DC converter
International Journal of Circuit Theory and Applications, 2021AbstractTo overcome the problems associated with Z‐source‐based DC–DC converters, a quasi‐Z‐source (QZS)‐based high‐gain DC–DC boost converter with switched capacitors is proposed in this work. Z‐source‐based DC–DC converters have problems like low‐voltage gain, discontinuous input current, and high‐voltage stress on the active and passive components ...
