TL;DR: In this article, a segmented differential power processing (DPP) unit with maximum power point tracking (MPPT) control is proposed to maximize PV power generation while minimizing converter power loss.
Journal ArticleDOI
Spread-Spectrum Technique Employing Phase-Shift Modulation to Reduce EM Noise for Parallel–Series LLC Resonant Converter
TL;DR: In this paper, an enhanced phase-shift algorithm of the frequency modulation of the SST and a parallel-series structure for an LLC resonant converter are proposed to obtain a tight outputvoltage regulation under the spread-spectrum operation.
Journal ArticleDOI
Practical Design of Dual Active Bridge Converter as Isolated Bi-directional Power Interface for Solid State Transformer Applications
Hyun-Jun Choi,Jee-Hoon Jung +1 more
TL;DR: In this article, practical design considerations of a dual active bridge (DAB) converter are proposed by means of a detailed mathematical model based on the converter's steady state operations. But the design considerations should be taken into account to overcome the disadvantages of DAB converter, such as low efficiency caused by restricted soft switching capability and high circulating current at heavy load conditions.
