Sanken Electric Co. Ltd. (Durham, NC) is expanding its line of low EMI, high-efficiency power supplies with the new ADP 100WB Series with power factor correction. According to Sanken, the units are suited to a wide range of portable applications, including notebook computers, printers and instrumentation. Sanken's patented SMZ (Soft-switched Multi-resonant Zero-current switching) topology products is claimed to produce higher efficiency and lower controlled EMI than traditional designs.
