Dear Friends,

I am just back from Nuremberg and PCIM Europe was again a fantastic event. A more than decent number of visitors explored the 3 halls and what the 500+ exhibitors brought to Nuremberg. Sometimes I wonder if 3 days is really enough to see everything.

I would like to thank all the speakers on my panel on Wednesday. In fact, it almost looked like slightly more people came for GaN than SiC. If that is the case, that would be a first!
If there is anything to criticise about the event, it is the small number of seats on stage. Wide Bandgap is too important a technology, we must not miss any expertise. This is one reason why I originally started my Wide Bandgap Event in December. I will be back in Munich this year, stay tuned for more information!

Cover Story
SiC MOSFET Modules as Building Blocks for PV Systems with Integrated Storage and EV Charging

The world is facing challenges due to consequences of using fossil fuel energy sources. To address these challenges the energy sector is under transition. Transitions occur not only on the generation side of electric energy with a shift towards using more renewable energy sources, but also in the way that energy is utilised in the different sectors.

Wide Bandgap
Improving Performance While Reducing Size and Cost with Monolithic GaN Integration

Gallium Nitride (GaN) heterojunction field effect power transistors in the 15 V to 350 V range have shown to give significant advantages over silicon in efficiency, size, speed, and cost in applications such as power conversion, motor drive, and pulsed light for lidar. These advantages are due to the critical electric field being an order of magnitude higher than in silicon, specifically a 3x advantage in band gap, and 1.3x advantage in electron mobility.

Design and Simulation
Advanced Inductor Circuit Models, Part II – Finding the AC Resistance

Part II of advanced inductor modeling describes how to obtain the proper ac resistance of the inductor winding. The final accurate circuit model of the inductor was found by making lab measurements of the ac resistance, which incorporates all loss mechanisms. Proximity analysis alone does not show all the measured losses.

Design and Simulation
Benefits and Challenges of Custom ASIC Development for Electronic Systems

An integrated circuit (IC), also known as a "chip," is a miniaturized electronic circuit comprising interconnected semiconductor components commonly made of silicon. IC technology has transformed the electronics industry by allowing a large number of electronic components to be integrated into a single chip which can then be mounted onto a printed circuit board (PCB) and connected to other chips and circuits to form a complex electronic system.

Power Management
Understanding Quiescent Current and Shutdown Current with a Boost Converter

For battery-powered applications, an excellent user experience depends on a long battery life and high-performance terminal devices. Quiescent current (IQ) is an important parameter to consider when optimizing these applications; in particular, an improved IQ increases battery life. This article will describe the difference between a boost converter's IQ and shutdown current (ISD) to provide a deeper understanding of how IQ and ISD can be utilized in battery-powered applications.

Capacitors
Back to Basics: Capacitors

The humble capacitor, a key passive component, is an essential item used in their tens or hundreds in virtually every electronics-based design. As students, we learn their prime circuit function, but rarely do we fully appreciate some of the factors that make them become a less than ideal component. This article highlights the critical characteristics of capacitors and some of their use cases, explains the different types available, the terminology, and some of the factors that make the capacitors exhibit completely different features.

Wide Bandgap
Variable DC-Link Voltage LLC Resonant DC/DC Converter using GaN HEMTs and SiC Diodes

The demand for efficient DC/DC converters continues to rise, with the industries focusing on optimal power consumption from the target devices. Compared to other converters, LLC resonant converters promote lower switching losses as the circuit switches the frequency at zero input voltage. Additionally, the continuous current source with minimal ripples reduces the EMI of the overall conversion.

Battery
Wireless Battery Management Systems - Enabling Smart Battery Ecosystems Solutions Through Higher Battery Performance, Greater Lifetime, and Cost Value

Electrification of passenger cars and commercial vehicles is entering a new phase of market penetration. The shift away from technology feasibility demonstration to the mass production of premium vehicles is obvious. The commercialization of technology leads to more optimized and affordable vehicles.
