The article also examines how adding iCoupler® isolated RS-485 transceivers provides a safe, reliable, and EMC robust solution for solar PV network communication interfaces.
IC Ecosystem for Driving Next-Generation SiC/GaN Power Converters
This Analog Devices article is electric. Literally. It highlights how SiC/GaN power switches are fueling everything from renewable electricity to electric-powered automobiles. These next-gen power converters are the key to delivering elevated voltages, better power density, higher working frequencies, and improved efficiency.
Isolated Gate Drivers – What, Why, and How?
An IGBT/power MOSFET is a voltage-controlled device that is used as a switching element in power supply circuits and motor drives, amongst other systems. The gate is the electrically isolated control terminal for each device. The other terminals of a MOSFET are source and drain, and for an IGBT they are called collector and emitter. To operate a MOSFET/IGBT, typically a voltage has to be applied to the gate that is relative to the source/emitter of the device. Dedicated drivers are used to apply voltage and provide drive current to the gate of the power device. This article from Analog Devices discusses what these gate drivers are, why they are required, and how their fundamental parameters, such as timing, drive strength, and isolation, are defined.
New IC Technology Boosts Performance of Large Lithium Ion Battery Packs
16kW-hr battery packs made from lithium ion cells are powering electric vehicles and storing grid energy. Measurement ICs like Analog Devices’ (https://www.arrow.com/manufacturers/analog-devices) LTC6804 are used to extend the life and ensure the safety of the pack. This video shows how the accuracy of the measurement IC can influence the cost of the system.
