What do new applications need in order to take advantage of new devices like wide band-gap semiconductors? They need the best inductors. And what is the best inductor for your application? Answering that requires proper characterization of the inductors, which is more than can be conveniently obtained

At the medium-to-low end of the power spectrum there are modest power conversion requirements such as those commonly found in “Internet of Things” (IoT) equipment, which necessitate the use of power conversion ICs that deal with modest levels of current. These are usually in the range of 100’s milliamps
Figure 1: Electric Vehicle Charging
An electric vehicle contains many sub-systems that need to inter-operate so the vehicle can function as intended. These disparate systems range from the battery string, comprising Lithium-Ion modules to various drive systems, converters, auxiliary modules, and charging and monitoring systems. As a result, choosing

With capabilities including high cycle life and fast charge and discharge times, small-cell supercapacitors can oust coin-type batteries from back-up power duties in equipment ranging from IoT devices, smart meters, or medical devices, to automotive electronics and industrial computing. Typical applications

In the more compact portable and wearable devices now being introduced onto the market, it is extremely difficult, or even impossible, to incorporate a charge connector. For example, some may simply have too little available space in which to house an appropriate connector. Other devices may require sealed enclosures
Sometimes described as the fourth industrial revolution, a new wave of technology is sweeping through industry. What was originally part of a 2020 strategy plan adopted by the German Federal Government has now spread across Europe, disrupting manufacturing and factory automation. There are now 159 organisations
Figure 1. Holter Heart Monitor
If you have ever visited your doctor suffering from symptoms even mildly suggestive of a cardiac problem, you may have been subjected to the “pleasure” of wearing a Holter heart monitor (Figure 1). After subsequent sleepless nights, you probably asked yourself, “Surely there must be a more comfortable

The healthcare industry is naturally transforming - even in the patient realm, as we see a continued increase in age, lifestyle-related conditions and levels of outpatient/home care. As can be imagined, this ongoing transformation translates into how we use technology and its impact on a vast range of applications.
Figure 1 - Creepage and clearance example (UL60601-1)
Power supplies for medical equipment must comply with IEC/UL 60601-1 3rd edition. Within this standard there are three categories of equipment. B-rated equipment will have only brief contact with a patient – for example an MRI scanner. BF-rated equipment will have routine contact with the skin;

The market for medical electronics is huge and growing. The astounding capabilities of digital technology and broadband connectivity are “a perfect storm” enabling doctors to diagnose more accurately and offer therapies more precisely than ever before. They also offer labor-saving benefits that
The updated IEC 60601 standard will bring some real changes including a focus on EMI and how medical equipment will be used in the home.
The latest standards for the development of medical power supplies are set to have a significant impact on how system designs are carried out, particularly in relation

The way consumers use personal exercise equipment at home is changing, and so are their expectations for that equipment, such as treadmills, ellipticals, and stair climbers. Today, they expect these machines to be as smart, connected, and sophisticated as machines found in their local gyms – if not more. The

In the days when bipolar transistors were the only option for semiconductor power switches, their base drive circuit was critical for fast and efficient operation. With power device gains often just in double digits, base currents could be huge. Complex arrangements had to be used to drive current in and out
