Power supplies overcome harsh environments
In order to meet demand for power supplies that are reliable in harsh environments, MEAN WELL has introduced es the 600W power supply ~ HEP-600 series, and the charger unit ~ HEP-600C series. These two series employ the latest high efficiency circuit design that the working efficiency is up to 96% for HEP-600 and 95.5% for HEP-600C.
Automotive-qualified MOSFETs deliver 5.9mΩ RDS(on)
Based on the company’s most advanced COOLiRFET 40V trench technology, International Rectifier has announced two 40V automotive-qualified power MOSFETs. The AUIRFN8458 and AUIRFN8459 deliver benchmark on-state resistance (Rds(on)) for automotive applications such as pump motor control and automotive body control, which require high current performance from a compact device.
Commutation encoder reduces assembly time on BLDC Motors
A next-generation modular encoder series is now available from CUI Devices. The AMT31 series, using a capacitive code generation system coupled with a proprietary ASIC, generates standard U/V/W commutation signals for vectoring current to brushless motors. The technology employed allows the device to be particularly well suited to brushless dc motor applications subject to vibration and contaminants.
AEC-Q101-qualified rectifiers reduce switching losses
Reducing switching losses and over-dissipation in automotive and telecomms applications, Vishay has announced 27 4-10A FRED Pt Hyperfast and Ultrafast recovery rectifiers. The AEC-Q101-qualified devices combine extremely fast and soft recovery characteristics with low leakage current and low forward voltage drop, typically down to 0.72V in single- and dual-die configurations.
Power engineers struggle to overcome the same old problems
Power management is an increasingly important element of electronics design. Engineers face a variety of power management challenges as portable systems require increased battery life, whilst mains-powered systems need to address power consumption to reduce thermal issues, cut operating costs and to meet the environmental need for lower CO2 emissions. In a recent research project, Napier surveyed the readers of Electronic Specifier to understand ...

The TB67S269FTG bipolar stepping motor driver provides 50V and 2A for printers, office automation equipment, ATMs, amusement machines and home appliances.
How to charge supercapacitor banks for energy storage
Supercapacitors (SCs), also known as ultracapacitors and electric double-layer capacitors, are finding use in a variety of power management applications. In automotive applications such as start-stop systems with regenerative braking, SCs can provide the energy needed to engage the starter to restart the combustion engine as well as accept the kinetic energy recovered during braking.
Vishay's New 12 V Chipscale MOSFET Cuts Power Consumption for Ultraportable Applications
A new power MOSFET that will help decrease power consumption and extend battery usage in smartphones, tablets, wearable devices, and high-end notebook computers was released today by Vishay Intertechnology, Inc. The new chipscale MICRO FOOT p-channel Si8457DB provides the industry's lowest on-resistance at a 1.8 V gate drive for any MOSFET with a 1.6 mm by 1.6 mm footprint and is the only such device with a VGS = ± 8 V rating, which provid...
Victron Energy launches Battery Balancer
Victron Energy launches its new battery balancer. Not all batteries are created equal, and when multiple batteries are combined to create one large battery bank, the small differences between the batteries can cause problems that substantially shorten the life time. The battery balancer prevents this by actively correcting the imbalance. Besides correcting, it is also equipped with an alarm function to give a warning in case of a large deviation....
