What is a “Joule Thief” dc/dc converter?
In some applications, it can be useful to drain almost all of the energy of a single cell battery, well below the voltage where the battery is usually considered fully discharged or “dead.” That’s when a Joule Thief dc/dc converter can be attractive. The name implies that the dc/dc converter is stealing Joules of energy […]
Compact transformers for DC/DC converters
TDK Corporation presents the EPCOS E10 EM series, a new range of insulated SMT transformers that are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics. There are four models in the series, with basic winding insulation of a working voltage of 500 VRMS and reinforced insulation of 300 […]
Handling the 48-to-12-V stepdown
A multiphase, interleaved buck converter can reduce bus voltage down to something useful in data center server racks. Brad Xiao, Nazzareno (Reno) Rossetti Maxim Integrated Hyperscale data centers that dissipate hundreds of megawatts demand efficient power delivery beyond the ability of the traditional 12-V power supplies on old server motherboards. A data center on 12 […]
Picking reliable power supplies
A few basic parameters can be useful for selecting power supplies that must work dependably in specific application scenarios. Alex Karapetian Acopian Power Supplies Electronic devices require a reliable source that can supply power at all times. But power supplies are available in a wide range of voltage and current ratings. Engineers tasked with selecting […]
