Anoop Gangadharan, Yokogawa Europe
In the rapidly evolving area of power electronics, the need for reliable testing to enhance safety, efficiency and performance has never been greater. In sectors as diverse as renewable energy, electric vehicles and energy-efficient technologies, changing application needs and evolving industry standards call

Of all the “hot” electronics markets, none is hotter than the market for devices designed to interact with the Internet of Things (IoT). Currently, more than seven billion IoT devices are in use worldwide, and the number of active IoT devices is expected to grow to 22 billion by 2025. Virtually all of those

Keith Curtis, Microchip
The greatest challenge faced by both new battery chemistry and charging algorithm developers is obtaining an Application-Specific Integrated Circuit (ASIC) design. Without silicon, new batteries and new charging algorithms have no way to acquire customers, and without customers – or at least potential customer

Mike Roach, AEM Components (USA), Inc.
Electronic systems for automotive applications are subjected to among the harshest of environments – wide temperature variations, shock and vibration, exposure to humidity, water chemicals and salt. Traditionally, blade-type automotive fuses have provided the necessary fault protection, but as cars get “smart”

Steve Knoth, Senior Product Marketing Engineer – Power by Linear Products, Analog Devices
It is common for many battery-powered devices to require a wide variety of charging sources, battery chemistries, voltages and currents. For example, industrial, high-end feature-rich consumer, medical and automotive battery charger circuits demand higher voltages and currents as newer large-battery packs are
Figure 1. The Bel Power Solutions 350DNC40 is a 4 kW DC/DC Converter that creates DC voltages in hybrid and electric vehicles suitable to power low voltage accessories. Features include very high efficiency, high reliability, low output voltage noise and excellent dynamic response to load/input changes.
Frank Vondenhoff, Business Development Manager for eMobility/HEV at Bel Power Solutions
With innovative manufacturers developing and expanding their range of solutions, engineers have more reasons than ever to replace alternators with DC-DC converters in road transport applications.
Today’s eMobility and hybrid and electric vehicle manufacturers emphasize the efficiency, reliability

Hector Garcia, Power Specialist, Avnet Abacus
It is often assumed that in any product design, if you can use a standard ‘off-the-shelf’ power supply it will be the lowest cost option compared with a full custom or configurable part. It’s true that with today’s fast-paced product launches and upgrades, if a custom part is commissioned, the Non-Recurring
Anup Bhalla, VP Engineering and Zhongda Li, NPI Manager at UnitedSiC
Today’s hybrid and fully electric vehicles (EVs) are still in the early stages of the iterative process of innovation. Several generations of hybrid vehicles have been introduced to market and improved through a combination of technology advances and user feedback. A number of vendors now market competent

ROHM has recently launched the BD9S series of secondary synchronous Buck DC/DC converters qualified to AEC-Q100 for automotive applications. These offer high reliability and low power consumption in a compact form factor. This makes them very suitable for applications like radars, cameras and sensors which can
Steve Hughes, Managing Director, REO UK
For years, the adoption of electric vehicles (EVs) has been marred by a slow diffusion of innovation among consumers. Probably the most obvious problem is that buyers have been apprehensive of the high initial cost of buying EVs, as well as the total cost of owning an electric vehicle over the course of its

John Grabowski, EV/HEV Systems Applications Manager, ON Semiconductor
With the very recent reassertion by scientists that the current trajectory for reducing the rate of global temperature increases is simply not good enough, there is now even greater pressure to reduce vehicle emissions of CO2 gasses. The best way of achieving this is through a reduction of the average
