Component-Minimized Buck-Boost Voltage Source Inverters

, 2007
This paper presents the design of buck-boost B4 inverters that can be derived from either Ćuk- or SEPIC-derived buck-boost B6 inverters. Unlike traditional inverters, the integration of front-end voltage boost circuitry and inverter circuitry allows it ...

Topology and Control Strategy of Lower Voltage Stress Single-stage Buck-boost Inverter

, 2023
Traditional non-isolated inverters based on the Buck-Boost principle usually have the disadvantage of high voltage stress. A new transformerless single-stage Buck-Boost voltage source inverter topology with lower voltage stress and its control method are

Demand Shocks, Export Diversification, and Firm Performance During the Great Trade Collapse

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper analyzes the impact of external demand shocks from the 2008 to 2009 Great Trade Collapse on the performance of Chinese exporters and examines how export diversification mitigates these effects. Using Chinese Customs data merged with financial data from all listed Chinese firms, we construct firm‐specific demand shocks based on pre ...

A MODIFIED VIRTUAL SPACE VECTOR MODULATION TECHNIQUE FOR Z-SOURCE NPC INVERTERS [PDF]

Carpathian Journal of Electrical Engineering, 2018
A modified virtual space vector modulation approach for the control of a Z-source neutral point clamped inverter is presented in this paper. This approach works perfectly for the traditional neutral point clamped inverter.

From Social Justice to Indigenous Peoples' Rights: Continuities and (Re)framings in Ejido Property Claims in Yucatán, Mexico

Journal of Agrarian Change, EarlyView.
ABSTRACT This article examines how long‐standing local conflicts concerning the nature of common property, the distribution of access and administrative rights associated with it, and more broadly the nature of the community and the forms of citizenship that organise its governance shape demands for justice regarding land transfers to outside investors

Learning in the Limit: Income Inference from Credit Extensions

The Journal of Finance, EarlyView.
ABSTRACT Combining a randomized controlled trial with administrative and survey data, this paper shows that credit limit extensions significantly increase total spending and income expectations. By controlling for changes in personal income expectations, the spending response to credit limit extensions weakens by approximately 30%.

Whose Rhetoric Matters? Social Responsibility Rhetoric and the Moderating Influence of Social Roles in Crowdfunding Pitches

Journal of Management Studies, EarlyView.
Abstract We use role congruity theory to examine how differing role expectations surrounding entrepreneur gender and race shape the influence of social responsibility rhetoric used in crowdfunding pitches. To do so, we develop a novel content‐analytic measure of social responsibility rhetoric using the Kinder, Lydenberg, and Domini (KLD) dimensions of ...

A Novel Single-Phase Flying-Inductor Buck-Boost Inverter

, 2019
In this paper a new single-phase flying-inductor buck-boost inverter is proposed. The inverter operates on the principle of flying-inductor, and it has the capability to buck or boost the input voltage without increasing the number of required components.

Modified modulation scheme of the buck-boost voltage source inverter for bidirectional power flow capability

, 2015
Single-stage DC-AC power converters are gaining higher popularity due to their merits compared to the conventional two-stage DC-AC conversion systems. One of these converters is the buck-boost voltage source inverter.

Entrepreneurial Market Leadership Claims, Cultural Resonance, and Investor Evaluations in Nascent Markets: The Goldilocks Effect

Journal of Management Studies, EarlyView.
Abstract Cultural entrepreneurship research emphasizes entrepreneurs’ use of cultural resources to influence audience evaluations through resonance. However, the process by which such cultural resonance is achieved remains underexplored, particularly as an intermediary outcome.
