Microchip unveils power control reference design to simplify AC/DC design

When used in smart home devices, offline AC/DC power relies on programmability and adaptive control to offer the flexibility and intelligence required to interface with the device’s power systems. In these systems, a secondary side microcontroller is typically not capable of starting a system without the use of a separate bias power supply. Microchip addresses this with a reference design which uses the MCP1012 high voltage auxiliary AC/DC controller. As a result, says Microchip, the independent bias power supply can be removed in many applications. The MCP1012 offline auxiliary device enables the system to transfer control of the power and duty cycle to a secondary microcontroller. The control between the system and the load can be more precise and purposefully coupled, through a design that can be simplified. This reduces size and cost, adds Microchip.

The reference design uses a patented isolation technique for isolated feedback. This patented Inde-Flux transformer technology is being licensed to Würth Elektronik eiSos. It is used in the Inde-Flux transformer (Part Number 750318659), which is sold as part of 15W MCP1012 offline reference design. The transformer combines the signal power and signal communication, eliminating the need for optical feedback or an independent signal transformer. The option is also available to use more traditional approaches with a planar pulse transformer on the reference design, as well as the ability of the design to work with more traditional optocouplers and signal transformers. The secondary side control is then enabled through a combination of the transformer and Microchip’s  MCP1012 AC/DC controller along with the SAM D20 series 32-bit microcontroller.

The MPC1012 primary side auxiliary controller provides for system start up, gating and protecting an offline flyback converter for the secondary microcontroller. The device enables a range of benefits such as direct measurement and active regulation of voltage and/or current, high loop bandwidth by direct loop closure and simplified communication for load-referenced systems.

The MCP1012 offline reference design provides the principal working elements for a 15W offline power design with the necessary firmware to enable the elimination of the auxiliary power supply on the primary side, Microchip explains. This can reduce the complexity of the system including eliminating the need for optocouplers in many applications such as appliances and smart speakers.

Inde-Flux transformer technology, in cooperation with Würth Elektronik eiSos, can be scaled to standard and custom transformer designs for different voltages and power levels as needed.

The 15W MCP1012 offline reference design includes a user guide and comes with schematics and bill of materials, design files, firmware, and a demonstration unit. Microchip also offers a fundamental 1W evaluation board, the DT100118, for the MCP1012 AC-DC controller.

ETSI lets edge app developers play in the Sandbox

To help application developers to experience and interact with an implementation of ETSI MEC APIs and test out their applications, ETSI offers the MEC Sandbox.

The interactive environment enables users to learn and experiment with ETSI MEC Service application programming interfaces (APIs). Standardised RESTful APIs are targeted at multi-access edge computing (MEC) application developers to consume the value-added services offered by MEC, including real-time access to network and context information (either fixed or mobile), as well as location information on infrastructure and user equipment.

The design principles for developing the APIs have also been specified in ETSI GS MEC 009, along with http methods, templates, conventions and patterns. The MEC service APIs are available in YAML and JSON format, presented via OpenAPI-compliant descriptions.

“With the Sandbox, developers with existing applications can configure them to access and use the live MEC APIs running in their own test environment which is essential for them,” explained Walter Featherstone, chair of the ETSI MEC Deployment and ECOsystem Development (DECODE) working group.

MEC Sandbox provides the user with a choice of scenarios combining different network technologies (4G, 5G, Wi-Fi) and terminal equipment, such as vehicles, pedestrians or connected objects. Combining these simulated assets in a geo-located environment, a user can gain hands-on experience of the behaviour and capabilities of the location (MEC013), radio network information (MEC012) and WLAN information (MEC028) service APIs.

Developers will be able to browse the Wiki Ecosystem page, which provides information mainly related to the work of the ETSI ISG MEC Deployment and ECOsystem DEvelopment (DECODE) Working Group, whose aim is to accelerate the development of the MEC ecosystem.

ETSI provides members with an open and inclusive environment to support the development, ratification and testing of globally applicable standards for ICT systems and services across all sectors of industry and society.  It is a not-for-profit body with more than 900 member organisations worldwide, drawn from 65 countries and five continents. Its membership is made up of large and small private companies, research entities, academia, government and public organisations.

ETSI is officially recognised by the EU as a European Standards Organization (ESO).

Semtech and GSA Optimise Logistics and Inventory Management with LoRaWAN®

Semtech Corporation has announced that Green Scale Alchemy (GSA), a leading developer of Internet of Things (IoT) solutions for asset management in the retail and supply chain industries, has integrated Semtech’s IoT devices operating on the LoRaWAN® protocol into its IoT-based pool management platform. The platform enables accurate pallet management to increase logistical efficiency and has already been rolled out by Giffard, a large-scale French liqueur manufacturer, to remotely manage its packaging assets and tools across two of the company’s large warehouses.

“By integrating IoT devices operating the LoRaWAN protocol, GSA is among the first in Europe to offer private networking capabilities and flexible devices to meet the needs of today’s supply chain managers,” said Frédéric Sammut, CEO at GSA. “Leveraging the LoRaWAN protocol provides accurate inventory data over long range, enabling managers to increase the efficiency of their logistical processes to reduce associated costs and increase sustainability.”

“GSA’s innovative solutions based on the LoRaWAN protocol enabled Giffard to transform its existing packaging and pallets into connected assets through innovative and simple retrofit. This allowed improved fleet management and the allocation of resources with integrated tools for more efficient production,” said Pierre Jouanneau Giffard, COO at Giffard. “Increased management efficiency allowed Giffard to optimise its workforce and material resources to improve profits.”

A standard in the logistics industry, wooden pallets deliver an estimated 95 percent of Europe’s consumer goods. GSA identified the shortcomings of legacy pallet-based shipping and developed its solution to leverage LoRaWAN networks to optimize the remote management of pallets in real time.

GSA’s platform based on the LoRaWAN protocol delivers comprehensive insight into the location and environmental status of the individual pallet, including geolocation capabilities to identify pallet location in a warehouse or in transit. This reliable data enables managers to track assets through the supply chain from manufacturing to distribution and out for delivery. Additionally, amid the ongoing COVID-19 pandemic, smarter logistics management and geolocation in warehouses allows organisations to move assets only when necessary and keep employees safe through social distancing.

In June 2017, Giffard deployed GSA’s solution to its newest liqueur production plant, a state-of-the-art site that manufacturing up to 20,000 bottles per day. The plant consists of two 3,000 square meter buildings dedicated to liqueur production and warehousing respectively. By utilising the IoT platform, Giffard receives and audits its production data to identify inefficiencies in its warehousing workflow and as a result remotely manages all its packaging assets and tools within its sites.

“Integrating proven IoT geolocation solutions operating on LoRaWAN enables customers to reduce logistical inefficiencies and reduce cost,” said Marc Pegulu, Vice President of IoT Product Marketing in Semtech’s Wireless and Sensing Products Group. “By developing its solution to utilise the LoRaWAN protocol, GSA created a flexible, scalable IoT platform that monitors and reports pallet status, condition and location in real time. These enhanced metrics help keep inventory safe and accounted for throughout the management cycle and deliver customers a faster ROI.”
