A transient dc-bias current due to the voltage-second imbalance of isolated bidirectional dual-active-bridge (DAB) converters for disturbance in line or load may result transformer saturation and oscillations both sides dc currents. This article focuses on elimination by using an improved triple-phase-shift (ITPS) control DAB converters. The inductor peak stress optimization is adopted proposed ITPS determine steady-state phase-shift variables. Originated from model with TPS control,...
Abstract Collecting electrophysiological (EP) signals (e.g., electrocardiogram (ECG), electromyogram (EMG)) during exercises is crucial for feedback of cardiac health and muscle injuries. However, since several interferences exist in the skin interface deformation, perspiration, motion artifacts), commercial rigid electrodes/systems have difficulty recording high‐fidelity EP signals. Here, a wireless Nepenthes ‐inspired hydrogel (NIH) hybrid system developed high‐quality signal detection by...
To eliminate the dc-bias current in transient-state (TS) of dual-active-bridge (DAB) DC-DC converter with load change demand, this paper proposed an optimized transient modulation (OTM) control strategy under triple-phase-shift (TPS) for response. Compared traditional algorithm TS, a fixed switching state is applied to increase transition speed and simplify complexity calculations. Because state, gradient inductor modified maximum value rather than piecewise linear relationship within...
Transient dc bias current exists in the power transmission of dual-active-bridge (DAB) converters under traditional control. The effects arising from transient include increased losses DAB and possible transformer saturation. Moreover, high overshoot might even damage converter. This paper aims to eliminate converter triple-phase-shift (TPS) An optimal control scheme TPS is proposed validated by both simulation experiments.
For the battery management system (BMS), accurate state of charge (SOC) estimation plays an important role in enhancing efficiency and ensuring safety battery. Considering tradeoff between accuracy SOC computational complexity, this paper proposes a multi-scale dual moving horizon (MHE) algorithm, which incorporates estimator model parameters using different time scales. Firstly, state-space models are built on basis equivalent circuit parametric sensitivity analysis, respectively. Secondly,...
This paper proposes an enhanced intermittent modulation (EIM) method with discontinuous current mode (DCM) to enhance power efficiency of a 700-V 20-kW three-phase dual-active bridge (3p-DAB) converter during light load operation. The 3p-DAB using traditional phase shift (PSM) will lose soft switching feature under low condition, resulting in significant reduction condition. Simulation results the non-ideal Simulink and PLECS software have shown that proposed EIM-DCM is effective improving...
