International Journal of ADVANCED AND APPLIED SCIENCES, 2017 In this paper, a novel buck-boost converter with the voltage gain of 2?1/1? is proposed. Output voltage is positive and the voltage stresses on the power switches and the diodes are low. Suggested topology is based on conventional boost converter. Proposed converter can provide a large step down voltage conversion ratio.

Symmetry and Duality in ZCS and ZVS Quasi-Resonant Buck, Boost, and Buck–Boost DC–DC Converters
EnergiesQuasi-resonant (QR) DC–DC converters with PWM control achieve soft switching by shaping the commutation transient through a local resonant process. This paper proposes a symmetry-based unified perspective on classical QR converters by interpreting zero ...

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa
Agribusiness, EarlyView.ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

Alternative Policy Designs to Help Farmers Select Profitable Conservation Practices
Agribusiness, EarlyView.ABSTRACT Voluntary private carbon initiatives (VPCIs) promote the implementation of agricultural conservation practices that mitigate emissions of greenhouse gases (GHGs) via financial incentives to participating farmers. Simultaneously, an array of public policies supports the adoption of conservation practices through technical and financial ...

Cost‐Benefit Analysis of the European Union Carbon Border Adjustment Mechanism in Fertilizer Trade
Agribusiness, EarlyView.ABSTRACT The carbon border adjustment mechanism (CBAM), launching 2026, will charge EU importers for embedded carbon emissions, aiming to reduce emissions but raising import costs. Shifts in demand following implementation may reduce carbon emissions, but importers will bear the cost of increased prices.
