Power Supplies and Converters

Tools and Software
There is no secret when designing a power supply or a converter: regardless of the final use, they must provide high efficiency to meet requirements set by national and international initiatives including 80 PLUS®, ErP Lot 6 and Energy Star as well as power density, reliability and safety and all this at the appropriate price point.  To find the best solution for their applications, designers have to choose the most efficient power topology – fly-back, boost, or quasi-resonant – or the implementation – based on monolithic ICs or with discrete power switches and controllers – or even decide to use an advanced digital implementation.
