Advantages of Advanced Active Clamping

چکیده
Power semiconductor manufacturers are offering IGBT modules with ever greater power densities. The limit is represented by the maximum power loss that can be dissipated; optimisation criteria are the packaging technology as well as the conduction and switching losses of the semiconductor chips. The high current density of the modules together with high switching speeds place increased demands on the driving circuits, both in normal switching operation and under overload conditions. Advanced Active Clamping switching technology offers a solution showing how modern high-power IGBTs can be better utilised.

Is "Delayed Umbilical Cord Clamping" Beneficial for Premature Newborns?
Background: The appropriate moment for clamping the umbilical cord is controversial. Immediate cord clamping (ICC) is an item of active management of the third stage of labor (AMTSL). Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC) of preterm neonates results in be...

متن کاملZero Voltage and Zero Current Switching dc-dc converter with active clamping technique
The zero voltage and zero current switching dc-dc converter with active clamping technique is proposed. By adding a secondary active clamp and controlling the clamp switch moderately, ZVS (for leading leg switches) and ZCS (for lagging leg switches) are achieved without any lossy components, the reverse avalanche break down of leading-leg IGHTs or the saturable reactor in the primary. Many adva...
متن کاملA New Family of ZVS-PWM Active-Clamping DC-to-DC Boost Converters: Analysis, Design, and Experimentation
The purpose of this paper is to introduce a new family of zero-voltage switching (ZVS) pulse-width modulation (PWM) active-clamping dc-to-dc boost converters. This technique presents ZVS commutation without additional voltage stress and a significant increase in the circulating reactive energy throughout the converters. So, the efficiency and the power density become advantages when compared to...
