The latest generation of Peltier cooling modules can be a powerful addition to a designer’s thermal management toolbox. Robust and reliable, they can cool an IC or various other components – such as an LED or laser diode – to a target temperature and ensure stability even if the load changes rapidly. The modules are […]

Demo: Gate drivers and eGaN transistors on the same chip
We recently did a short video with Alex Lidow from EPC who took us through a demonstration of a gate driver integrated onto the same chip as eGaN transistor. Driving the gate of the power transistor is complicated because of the parasitic elements. Lidow explained that eGaN transistors switch in a nanosecond or less, and […]
Trends in discrete power semiconductors
For many years the rumored demise of the discrete semiconductor has been thrown around, says Joe Beck from Central Semiconductor. Everything’s going to be integrated into an IC. It’s all going away. Not true. In fact, there’s more interest in discrete today than in the last 10 or 15 years, Beck says. When engineers try […]
Tips on selecting toroidal inductors
Anthony Kourtessis from Signal Transformer, a Bel Group, recently went through some of the things you need to keep in mind when selecting toroidal inductors in a short video with us. First and foremost, he said, you need to establish which product will give the greatest energy storage capability. In addition, you’re looking for a […]
The benefits of silicon carbide in dc/dc converters
Adil Salman from Wolfspeed recently shot a video with us covering a silicon carbide charging circuit demonstration. The charger used Wolfspeed SiC MOSFETs. It had two stages. One is a PFC (power factor correction) stage, the other is an LLC converter stage. If you were to try building a similar charger with silicon IGBTs, you […]
SMPS chips from Analog Devices squelch EMI
We recently filmed a short video with Tony Armstrong from Analog Devices who took us through a demonstration of a new kind of circuitry that cuts down the noise from switching power supplies. Switchers are notoriously noisy but can usually be fixed with filtering. Armstrong illustrates that with a non-synchronous regulator running at about 300 […]

Simulating electric motors with MotorSolve software
We recently filmed a short video with Chad Ghalamzan from Infolytica, which is now part of Mentor Graphics, a Siemens business. Infolytica develops simulation software called Motorsolve for magnetics as you might find in motors used in electric vehicles. Motorsolve is electric motor design software that allows an engineer to do virtual prototyping of their […]
Power rail analysis using high-definition scopes
Ken Johnson from Teledyne LeCroy recorded a short video with us recently on an eight-channel Teledyne LeCroy scope which was being demoed displaying power signals from a little demo board. The scope was the LeCroy eight-channel, 12-bit, one-gigahertz oscilloscope. In the demo, it displayed five power rails and a current signal and a digital clock […]
Grid links get more compact thanks to gallium nitride
Serkan Dusmez from Texas Instruments recently recorded a short video with us on a gallium-nitride based grid link. It is a three-phase, three level bidirectional grid tight inverter developed jointly by Texas Instruments and Siemens. It includes 600-V GaN TI drivers that incorporate smart features like over voltage protection and over temperature protection in a […]
