    For efficiencies’ sake – how to integrate bidirectional power flow into your UPS design (part 1)

    With a growing emphasis on more compact, smaller and more efficient power systems, there is increasing interest in bidirectional converters. A bidirectional DC/DC converter, capable of bidirectional power flow, can combine the two DC/DC converters traditionally required for battery charging and backup operations into one. This brings down the cost,...

    Do you have the correct PFC to meet the new standard of harmonic current emissions standards?

    International Electrotechnical Commission (IEC) 61000-3-2: 2014 is a new standard of electromagnetic compatibility (EMC) that supersedes IEC 61000-3-2: 2006 and will be enforced as of June 30, 2017. This part of the standard deals with the limitation of harmonic currents injected into the public supply system. It specifies limits for harmonic components...

    Small doesn’t mean you compromise performance

    A couple of years ago, when I was working with interfaces in the industrial market, the size of the device package was never a showstopper. Fast-forward a few years, and device package size is sometimes a deciding factor as to whether you can use it in your application. Industrial application functionality is increasing while size is decreasing,...

    Increasing battery life in IoT devices

    Wireless sensors are gaining popularity with the installation of more smart devices in homes and buildings. Battery-powered wireless devices enable very easy installation almost anywhere, but changing batteries frequently is not ideal from an ease-of-use or cost perspective. For example, if you retrofit a commercial building with wireless sensor nodes...
