GaN is cost-effective in motor drive applications
By Eric Persson, Senior Principal Engineer AC-DC Applications, Infineon Technologies We take motors for granted – they have been with us since Benjamin Franklin experimented with electrostatic types nearly three hundred years ago – but the days are long gone when they were controlled in a simple on/off way. Motors in today’s applications, from clothes […]
Tiny eGaN FETs target BLDC motor drives, Lidar apps
EPC advances the performance capability while lowering the cost for off-the-shelf gallium nitride transistors with the introduction of EPC2065 and EPC2054. The EPC2065 is an 80 V, 3.6 mΩ, 221 Apulsed eGaN FET in a 7.1 mm2 chip-scale package. The small size and superior efficiency reduce overall power system size and weight and make it […]

GaN transistors, ICs feature radiation hardening
EPC announces the introduction of a new family of radiation-hardened gallium nitride transistors and integrated circuits. With higher breakdown strength, faster-switching speed, higher thermal conductivity, and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices. The lower resistance and gate charge enable faster power supply switching frequencies resulting in higher power densities, higher […]
Basics of motion-control profiles, Part 2: Ramp profiles
How a motor ramps its angular position or rotational velocity from a starting point to the intended target value is a complicated topic which modern motor controllers address in many ways. Part 1 was an introduction to issues related to motor and motion control. This part will focus on the topic of motor ramping and […]
Basics of motion-control profiles, Part 1: Context
How a motor ramps its angular position or rotational velocity from a starting point to the intended target value is a complicated topic which modern motor controllers address in many ways. Controlling the motion of a motor is a major design challenge since how a well a possible motor choice can ramp its speed and […]
optical-isolated IGBT, power module drivers fit in cramped quarters
Renesas Electronics Corporation expanded its family of 8.2mm creepage photocouplers with three new devices designed for operation in harsh industrial automation equipment, solar inverter, and EV charger operating environments. Measuring a mere 2.5mm x 2.1mm in an LSSO5 package, the world’s smallest optical isolated IGBT drivers and intelligent power module (IPM) driver reduce PCB mounting […]
