OBJECTIVE Neutropenia is the most frequent side effect of cotrimoxazole in sub-Saharan Africa. We estimated the incidence of haematological disorders during the first 6 months of a zidovudine-containing highly active antiretroviral therapy (HAART) regimen in sub-Saharan African adults receiving cotrimoxazole. METHODS Prospective cohort study in Abidjan,(More)
A quasi-Z-source three-phase rectifier is analysed by deriving its detailed dynamic model using circuit averaging and the synchronous reference frame. The quasi-Z-source provides the same advantages as the Z-source rectifier as well as additional advantages such lower rated capacitors. The quasi-Z-source rectifier contains non minimum phase zeros in its(More)
Capacitor-switching operations found in magnetic-less DC-DC converters lead to significant capacitor power loss while capacitor voltage unbalance leads to high peak currents in the capacitors and switches. Power loss leads to premature failure of capacitors and is inversely proportional to both capacitance and switching frequency. A given reduction in(More)
