    Easy Integration of Supercapacitor Power Back-up

    Frederik Dostal, Subject Matter Expert, Power Management, Analog Devices

       One of the major trends over the last two decades is to replace mechanical systems with electronic systems wherever possible. Deploying an electronic system usually has the advantage of offering faster and more accurate responses, while being more reliable due to having no physical wear and te

    Figure 1. A complete 12 V isolated flyback converter for a wide input from 20 V to 800 V with a minimum start-up voltage of 260 V

    ­In traditional isolated high voltage flyback converters, tight regulation is achieved using optocouplers to transfer  regulation information from the secondary-side reference circuitry to the primary side. The problem is that optocouplers add significant complexity to isolated designs: there is propagation de

    Figure 1: Ac charging diagram

    ­EVs can now achieve similar mileage as gas-powered vehicles, but it still takes more time to charge an EV than to refuel a gas vehicle. Charge time is approximately equal to the amount of energy delivered to the battery divided by the charging power; therefore, it is desirable to use as much power as possible to

    Figures 1a: Filtering normal-mode

    ­EMI-RFI filters are needed to attenuate common-mode and differential-mode EMI (or noise). Although simple in principle, they are not easy to design and often require specialist help. Moreover, in three-phase power applications, adequate filtering can occupy a large volume. An integrated three-phase filter ca
