Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

open access: yesAdvanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Dual-Loop Voltage–Current Control of a Fractional-Order Buck-Boost Converter Using a Fractional-Order PIλ Controller

open access: yesFractal and Fractional, 2023
Based on the fact that the inductor and capacitor are of a non-integer order by nature, to provide a more accurate theoretical basis for the optimal control of the converter, the fractional-order model of the Buck-Boost converter in the continuous mode ...

Integrated design & control of a buck boost converter [PDF]

open access: yesSba: Controle & Automação Sociedade Brasileira de Automatica, 2009
This paper presents the integrated design and control of a buck boost converter (BBC). In the proposed methodology the design tool provides simultaneously the controller tuning and BBC design parameters in such a way that some closed-loop pre-specified static and dynamic behavior is obtained.

A unified analysis of PWM converters in discontinuous modes [PDF]

open access: yes, 1991
Three discontinuous operating modes of PWM (pulsewidth modulated) converters are considered: the discontinuous inductor current mode (DICM), the discontinuous capacitor voltage mode (DCVM), and a previously unidentified mode called the discontinuous ...

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Comprehensive analysis and design of a switched‐inductor type low inductance‐requirement DC‐DC buck‐boost converter for low power applications

open access: yesIET Power Electronics, 2023
This paper aims to comprehensively analyze, critically discuss, and provide a step‐by‐step design guideline for a previously proposed Modified Switched‐Inductor type Buck‐Boost (MSIBB) converter which is based on a boost converter. The MSIBB converter is

Interleaving double-switch buck–boost converter

open access: yesIET Power Electronics, 2012
The double-switch buck-boost converter, characterised with non-inverting and step-up/step-down conversion, is suitable for the front stage of the two-stage photovoltaic (PV) grid-connected inverter. However, one strategy for the converter, named as 'synchronisation control', requires a considerable inductor and another control strategy, named as ...

Unpacking the Farmland Capitalization Effect of Ethanol Establishment

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We unpack the impact of expansions in ethanol production—as measured by proximity to newly constructed ethanol plants and capacity expansions—on farmland values using land transaction data from Kansas in combination with modern causal inference techniques.
