AC-DC efficiency measurements need to include power factor
Power converter designers compete to minimise losses, chasing the last decimal points of efficiency, η, the ratio of output to input power. But when it comes to calculating efficiency in AC-DC power supplies mistakes are often made as a result of omitting or improperly measuring power factor, which is why it is important for designers to understand power factor basics and how to incorporate it.
The first in a new breed of neural network acceleration SoCs
BrainChip Holdings has brought spiking neural network architecture – the AkidaNeuromorphic System-on-Chip (NSoC) – to market.This architecture helps the acceleration of AI at the edge and the enterprise. The Akida NSoC is small, low cost and low power, making it well suited for edge applications such as ADAS, autonomous vehicles, drones, vision-guided robotics, surveillance and machine vision systems.
5W AC/DC modules for industry 4.0, IoT and smart home
RECOM has expanded its low power AC/DC portfolio with encapsulated 5W power supplies, which operate up to +90°C. They accept input voltage lines of up to 305VAC and offer peak power capability up to 6W. These modules are suitable for Industry 4.0, IoT and smart household applications requiring features that go beyond the industry standard.
Polymer capacitors versus multilayer ceramic capacitors
Capacitor selection seems a simple choice but demands, challenges and expectations of modern electronics prove otherwise, explains Panasonic Industry Europe
Compact GaN driver cuts power supply size by up to 80%
The LMG1020 gallium nitride (GaN) driver from Texas Instruments is available from Mouser Electronics. The single, low-side driver enables efficient, high-performance designs in speed-critical applications such as LiDAR, time-of-flight laser drivers, facial recognition, augmented reality, and class E wireless chargers.
TBMS rectifiers reduce power losses, improve efficiency
Four 100V and 120V TMBS (Trench MOS Barrier Schottky) rectifiers that provide up to 20mV lower forward voltage than previous-generation devices have been released by Vishay Intertechnology. The Vishay General Semiconductors V30100CI, V30120CI, V40100CI, and V40120CI offer current ratings of 30A and 40A in the TO-220AB package.
Simple to implement, ultra compact, DC/DC converter series
It has been announced by Luso that HVM Technology have released the SK Series of miniature single-output, fully regulated DC to DC converters. They supply up to five kilovolts at one watt in an ultra compact package of less than one cubic inch and are suited for various applications, especially those with size constraints.
