Avnet Abacus is extending its distribution agreement with Panasonic to include RF and wireless module based products and technologies which cover all the latestcommunication protocols with ready-to-use modules for Bluetooth, Bluetooth Low Energy and Wi-Fi. The focus is to help companies shorten their development cycle and gain faster time-to-market.

Most modern power conversion topologies use switched-mode techniques for highest efficiency and smallest size and cost. Inevitably, switching noise is produced and output filters are required to minimise EMI and provide reliable operation of the power converter and load. This article looks at the effects of noise and some of the filtering techniques that can be used.

In applications from the simplest cell-phone charger to grid-tied inverters operating at hundreds of kW, power conversion schemes are used which incorporate an intermediate stage where energy is processed at DC. A ‘DC-link’ capacitor is fitted at this point to provide a low impedance path for high frequency switching currents and to provide energy storage.

The threat of explosion is real in many industrial applications, from petrochemical refineries and cleaning facilities to flour silos and even landfill sites. While explosion is a hazard anywhere there is a flammable substance in the atmosphere in the form of gas, vapour or dust, the presence of the flammable substance on its own is not enough to trigger an explosion.

Supercapacitors are commonly used wherever a quick energy boost is needed, as an alternative to a rechargeable battery. The most prevalent type of supercapacitors, EDLCs (Electrical Double Layer Capacitors), providethousands or tens of thousands of times the capacitance of normal capacitors while their energy density makes them ten times smaller than batteries (more here about how EDLCs work in detail).

Today’s microprocessor-based systems require power sources that deliver high current and ultra fast transient performance, with tight regulation. This creates a need for cost effective, compact capacitors with high capacitance values. Electrolytic capacitors are the solution of choice but it’s important to go beyond specifying capacitance and voltage to consider Equivalent Series Resistance (ESR) as a figure of merit.

Availability of an EtherCAT starter kit for the development of a wide range of fast industrial Ethernet technology-based applications has been announced by distributor Avnet Silica.. Implementing the standard Ethernet data-packet format, which provides connectivity to existing Ethernet networks without special routers or switches, EtherCAT delivers highly-efficient, real-time performance enabling data insertion and/or extraction ‘on the fly...

Compact and cost-effective is how Avnet Silica describes the MiniZed Zynq SoC development platform. MiniZed provides an entry-level development and demonstration platform for single-core Xilinx Zynq-7000 All Programmable SoC devices. This cost-optimised solution supports cloud connectivity and industrial IoT applications such as motor control and embedded vision.

These days, a typical specification for a power converter starts with a list of international standards that must be met for EMC and safety compliance. The requirements for functional performance are often many pages into the document.

As data centres and data farms continue to expand and grow, better solutions are required for system architectures that allow faster communication and more efficient operation. The physical limits imposed by copper PCB traces are being reached - communication over copper is limited to around 10GBps, and at high speeds losses limit the distances to a few inches.
