Pouch-type EDLCs for thin-and-light circuit designs
Supercapacitors now come in a small, thin format that makes them candidates for uses characterized by cramped quarters. Shinji Higuma, TDK Corp. In the next several years, the internet of things (IoT) will include tens of billions of connected devices. Consumer, industrial, medical, and automotive applications will feature connected devices, but not all connected devices […]
Grid converter puts locally generated power on power grids
Siemens presents a new power conversion system for battery storage applications. The SINAMICS PCS grid converter makes locally generated batter power usable for industrial and public power grids. SINAMICS PCS controls the charging and discharging process of the battery and helps to handle load peaks and grid disturbances via the battery storage, to store the […]
Full bridge LLC transformer/resonant choke combo targets EV inverter apps
PREMO releases the new 11kW 3DPower solution, a Full Bridge LLC Transformer 150 µH + Resonant Choke 25 µH merged in 1 single unit. This innovation provides up to 40-50% reduction in volume compared with current discrete industrial solutions for the same power management. Most of the Power Converters (resonant topologies) in the market have […]
Lightweight dc/dc converters target fuel cell applications
With its new DCHV320 DC-DC converter, BrightLoop Converters is aiming to provide the best off-the-shelf DC-DC conversion solution to fuel cell vehicles by focusing on extreme power density and versatility. In a Fuel Cell Electric Vehicle (FCEV), the fuel cell produces electricity to power the high-voltage batteries needed to run the electric motor. However, fuel […]

Three-phase gate drivers geared for EVs and hybrids
Allegro MicroSystems, Inc. is expanding its QuietMotion product line with the introduction of the new A89307 automotive-qualified gate driver integrated circuit (IC). Designed for battery cooling fans and HVAC systems in electric (EV) and hybrid vehicles, the A89307 offers ultra-low noise and vibration by using a Field Oriented Control (FOC) algorithm to drive continuous sinusoidal current […]
Inductors target power-over-coax automotive apps
TDK Corporation announces the release of its newly developed ADL3225VM inductors for use in automotive Power over Coax (PoC) systems. Measuring at 3.2 x 2.5 x 2.5 mm (L xW x H), these inductors provide a compact solution for designers looking to reduce vehicle weight as manufacturers add more sensors and cameras to accommodate expanding […]
Reed relays handle continuous carry currents to 3A
Pickering Electronics has launched the Series 100 HC high power SIL/SIP reed relay that is rated for 1A switching at up to 40W and up to 3A continuous carry current. Featuring the highest quality instrumentation-grade switches with sputtered ruthenium contacts, Series 100 HC relays are suitable for low-level or ‘dry’ switching applications. Series 100 […]
Putting supercapacitors to work
There are a variety of modern applications in which supercapacitors are better candidates than either batteries or ordinary capacitors. George Wundsam, Cornell Dubilier Supercapacitors are not new. First developed in the 1950s, commercial versions were marketed over 40 years ago. At that time, supercapacitors were certainly not on a fast track to practical application. They […]
