95% High efficiency power supply changes the way high reliability systems are designed

The size or power density of a power supply is a key criteria when selecting the optimum product for a given application. In applications where fans are not desirable due to noise or reliability concerns then efficiency becomes of primary concern. Power supply technology has evolved to a point where efficiencies in the 90-95% range are available. To put this into context a typical power supply in the 1980’s would have been in the region of 75% efficient. ■
