Simplified Isolated Forward Converter

INTELEC '82 - International Telecommunications Energy Conference, 1982
This thesis pertains to a forward converter consisting only of primary-side control circuits for regulating the output voltage. Control circuits in a conventional forward converter for regulating the output voltage control the on and off times of primary-side switching transistor by comparing the output voltage directly with the reference voltage.

Isolated voltage-boosting converter

2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014
In this paper, a single switch isolated voltage-boosting converter is presented, which is derived from the traditional flyback converter and charge pump concept. The proposed converter possesses an output inductor, so the output current is non-pulsating.

Novel capacitor-isolated power converter

2010 IEEE Energy Conversion Congress and Exposition, 2010
This paper presented a novel power conversion method of realizing the galvanic isolation by dual safety capacitors (Y-cap) instead of conventional transformer. With limited capacitance of the Y capacitor, series resonant is proposed to achieve the power transfer.

Non-Isolated Interleaved Flyback Converter

2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2018
There is an ever-increasing demand for viable, clean, energy sources. The main obstacle in using solar energy sources is that the output voltage obtained is too low for practical use. The obtained output voltage should be stepped up considerably in connection with the utility mains.

Isolated high voltage‐boosting converter derived from forward converter

International Journal of Circuit Theory and Applications, 2015
SummaryA novel isolated high voltage‐boosting converter, derived from the traditional forward converter, is presented in this paper. As compared with the traditional forward converter, the demagnetizing winding of the transformer in the proposed converter is used not only to demagnetize but also to improve the voltage conversion ratio.

A W-Band Polarization Converter and Isolator

IEEE Transactions on Antennas and Propagation, 2007
A 95-GHz printed low-loss linear-to-circular polarizer is designed as a component of an active direct-detection millimeter-wave imaging system. The periodic printed grid structure presents different reactances to the TE and TM polarizations, resulting in equal amplitude and phase quadrature upon transmission through four parallel grids.

A new Isolated Hybrid Boosting Converter

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
A new Isolated Hybrid Boosting Converter (IHBC) is proposed in this paper. It employs fly-back structure at primary side of transformer and a Bipolar Voltage Multiplier (BVM) structure at secondary side to increase the voltage gain. The circuit alternates between forward and fly-back modes, which avoids the use of magnetic reset winding.

Isolated bidirectional switched-capacitor flyback converter

2014 International Power Electronics and Application Conference and Exposition, 2014
In this paper, high-efficiency, extremely high step-up and step-down bi-directional DC-DC converter is proposed. The proposed converter consists of a flyback and an isolated switched-capacitor cell to achieve high cost competitiveness for the extreme operation. The output of the flyback converter and that of the isolated switched-capacitor is connected
