High Efficiency PFC Choke

Posted on 30 June 2020

    Designed for PFC chipset application Did you realize that an electric car is a net plugged “apparatus” as per the description of the EMC Directive 2004/108/EC. To the eyes of the electric network the car is no different than a Washing Machine or a Plasma TV set. Charging your car battery will require [...]

Storage Capacitor Properties and their Effect on Energy Harvester Performance

Posted on 29 June 2020

      Best energy harvester performance using professional tantalum capacitors The development of energy harvesters has quickened up in the last few years mainly due to semiconductor improvements. But power sources for energy harvesters usually exhibit high internal impedance and can therefore only deliver low currents. The most important consideration for harvesting is that [...]
