The annual IEDM conference (www.ieee-iedm.org), sponsored by the IEEE Electron Devices Society, usually includes presentations covering noteworthy technological developments, and this year’s event is no exception. To be held December 1-5, 2018 at the Hilton San Francisco Union Square Hotel, it includes a talk by researchers from the National Institute of Advanced Industrial Science and […]
Power Electronics Top Talks in November on EDABoard.com forums
Peer-to-peer, engineer-to-engineer questions and answers from the EDABoard.com engineering community around power electronics. Click the “Read more” link and follow the entire conversation and maybe add your two cents by logging in to EDAboard.com Dell power supply – I got this PSU from one of my colleagues and did a quick inspection for the faults in […]
Power management ICs, part 2: PMIC implementations
The power management IC (PMIC) is often a vital part of the lower-voltage DC subsystem, as circuits have multiple power rails with tight individual specifications as well as mandated relationships among them. Part 1 of this FAQ discussed the need for, PMICs and their general characteristics. Part 2 now looks at specific ICs which implement […]
Power Management ICs, part 1: PMIC functions
The power management IC (PMIC) is often a vital part of the lower-voltage DC subsystem, as circuits have multiple power rails with tight individual specifications as well as mandated relationships among them. It’s one thing to develop needed low-voltage DC rails via DC/DC converters or regulators, but there’s also a need to manage these power […]
GaN FETs boost efficiency in electric vehicle chargers
The role gallium-nitride FETs play in the design of an EV charging circuit help illustrate how these wide-bandgap semiconductors facilitate energy efficiency. FENG QI, TRANSPHORM THE PHASE-SHIFT FULL BRIDGE (PSFB) is a classic topology for applications that must accommodate a wide range of operating voltages, as with battery chargers. A PSFB converter generally uses four […]
Don’t be led astray on three-phase power measurements
Measurements made on power analyzers may differ from those on another because different manufacturers employ different settings and wiring assumptions. KEN JOHNSON, TELEDYNE LECROY POWER ANALYZERS have been manufactured for many years and are used in a wide variety of applications. Often, the settings and preferences dialed in from the front panel can significantly impact […]
Energy efficiency, smart lighting, and the IoT
Sure, smart lighting will save energy, but they’ll also be the backbone of systems that can help minimize mini-catastrophes. CEES LINKS, Qorvo THE IoT (internet of things) INCLUDES a rich offering of energy efficiency benefits. Smart lighting is, of course, one of the most common elements of any IoT energy efficiency discussion. Lighting is a […]
Optimizing the energy efficiency of converters and controllers
Here’s how to evaluate energy efficiency associated with components that make up widely used power conversion circuitry. FRANK DE STASI, MATHEW JACOB, TEXAS INSTRUMENTS INC. IN SOME WAYS, selecting a module, converter or controller for power conversion resembles deciding whether to take a flight, board a train, or drive from point A to B. Once […]
Evaluating options for USB Type-C connections
Port controllers, transceivers, and special dc/dc converters now simplify the task of adding USB Type-C functions. DANIEL LEIH, MICROCHIP TECHNOLOGY INC. CONSIDER THE VIRTUES of the USB-C connector. In addition to its 10 Gbit/sec (Gbps) bandwidth and Alt Mode video capabilities, two attributes, in particular, make this form factor incredibly valuable: a reversible plug and […]
Capacitors in renewable energy
It pays to know the distinguishing features of electrolytic, film, and super capacitors when planning applications where energy efficiency is important. MORRIE GOLDMAN, ILLINOIS CAPACITOR INC. RENEWABLE ENERGY SYSTEMS all have a common need for high-efficiency power circuits. Whether the original source of energy is light, heat, or mechanical motion, ancillary circuitry will probably either […]
