Resonant CLL Non-Inverting Buck-Boost Converter [PDF]
Journal of Power Electronics, 2013 This paper presents a resonant non-inverting buck-boost converter in which all switches operate under ZCS conditions. In a symmetric configuration, a CLL resonant tank along with an inverter arm and a rectifying diode are employed. The diode is turned off at ZCS and hence the problem of its reverse recovery is obviated also.

International Journal of Finance &Economics, EarlyView.ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade
