Vicor launches ‘PowerTechtorials’ on CD
Vicor has launched a new educational initiative for power design engineers which provides support throughout the power systems design process from selecting the optimum architecture to meeting EMI regulations. The first phase, a series of ‘PowerTechtorials’ is now available on CD. Each CD serves as a one-on-one tutorial, containing technical presentations and lab demos, that can be revisited as needed. The tutorials address everyday technic...
Device Increases System Efficiency 1.5 Percent and Reduces Rectifier Device Temperature by 25 Degrees Celsius
International Rectifier, IR has expanded its family of SmartRectifier ICs with the introduction of the IR1168 for AC-DC power converters for high-end applications such as LCD TVs. The 200V dual smart secondary-side rectifier driver IC is designed to drive two N-Channel power MOSFETs used as synchronous rectifiers (SR) in resonant half-bridge topologies. In contrast to traditional current transformer SR methods, the IR1168 accurately determines tu...
