ANPC inverter design secures ‘sweet spot’ for PV

According to Infineon Technologies, the use of an advanced neutral-point-clamped (ANPC) inverter design supports an even loss distribution between semiconductor devices, compared with traditional three-level neutral-point-clamped topologies. The company has used the ANPC topology for its hybrid SiC and IGBT power module EasyPack 2B in the 1,200V family. It is claimed to optimise ‘sweet spot’ losses of Infineon’s CoolSiC MOSFET and TrenchStop IGBT4 chipsets respectively, with increased power density and a switching frequency of up to 48kHz. The inverters are suitable for the needs of new generation 1,500V photovoltaic and energy storage applications, adds Infineon.

The ANPC topology supports a system efficiency of more than 99 per cent. Implementing the hybrid Easy 2B power module in, for example, the DC/AC stage of a 1,500V solar string inverter allows for coils to be smaller than with devices with a lower switching frequency. This reduces the weight “significantly” compared with a corresponding inverter with purely silicon components, says the company. Additionally, the losses with silicon carbide are smaller than with silicon. For this reason, less heat must be dissipated so that the heat sink can also shrink. This results in smaller inverter housings and costs savings at system level. The design also reduces inverter design complexity, compared to five-level topologies.

The Easy 2B standard package for power modules is characterised by an industry-leading low stray inductance. The integrated body diode of the CoolSiC MOSFET chip ensures low-loss without the need for another SiC diode chip. There is also an NTC temperature sensor for monitoring and PressFit technology to reduce assembly time for mounting the device.

The hybrid EasyPack 2B can be ordered now.

Embedded edge computing modules exploit Intel processor technology

10 new COM Express Type 6 modules have been announced by congatec. They feature the latest Intel embedded processor technology, with four Intel Xeon, three Intel Core, two Intel Celeron and one Intel Pentium processors based on the same Intel microarchitecture (codenamed Coffee Lake H). This enables congatec to provide all 10 new processors on one COM Express module design – the conga-TS370.

This brings the total of processor module variants now available on this single microarchitecture to 14, offering wide scalability, points out the company.

The 45W six-core module with 2.8GHz Intel Xeon E-2276ME processor provides the highest embedded computing performance with integrated high-performance processor graphics currently available, claims congatec. The 2.4GHz Intel Celeron G4930E processor module with 35 watts sets a new price-performance benchmark, adds the company.

The two six-core congatec modules with a TDP of 25W offered on Intel Xeon E-2276ML and Intel Core i7-9850HL processors enable developers to create passively cooled embedded edge computing systems that can run up to 12 standalone virtual machines in parallel, via hyperthreading. This allows operation even in fully sealed systems, under the harshest environmental conditions and with the highest IP protection, asserts congatec. The same applies to the two quad-core modules with Intel Xeon E-2254ML or Intel Core i3-9100HL processor as well as the Intel Celeron G4932E processor-based module, all featuring a – partly configurable – TDP of 25W.

The company has released these modules in response to OEM customers using multi-core platforms to consolidate separate systems on a single embedded edge computer. Hypervisor technology allows customers to operate up to 12 virtual machines in parallel on one system, including real-time controllers (soft PLCs), industry 4.0 gateways for tactile internet via time synchronised networking, IoT gateways for sending big data towards the cloud and central management systems, as well as vision systems, artificial intelligence (AI) and deep learning applications. Software-defined networking functions such as intrusion prevention and detection systems that analyse data traffic parallel to the applications can avoid latencies that would arise with serial operation of analytics and applications, advises congatec.

In addition to embedded edge computing, they can be used in medical imaging systems and human machine interfaces (HMIs) as well as gaming, infotainment and digital signage systems.

Arm Flexible Access gives chip designers the freedom to experiment and test before they invest

Arm announced today it is expanding the ways existing and new partners can access and license its technology for semiconductor design. Arm Flexible Access is a new engagement model enabling SoC design teams to initiate projects before they license IP and pay only for what they use at production. Through Arm Flexible Access, businesses will enable their design teams with more freedom to experiment, evaluate and innovate.

“Arm Flexible Access was created to address the opportunities presented by a world of one trillion securely connected devices,” said Rene Haas, president, Intellectual Property Group, Arm. “By converging unlimited design access with no up-front licensing commitment, we are empowering existing partners and new market players to address new growth opportunities in IoT, machine learning, self-driving cars and 5G.”

Several partners, including AlphaICs, Invecas and Nordic Semiconductor, have signed on to this new Arm engagement model and already have access to a wide range of IP products, support tools and training. Arm Flexible Access complements standard Arm licensing which will continue to be the best option for partners seeking access to Arm’s full product portfolio and most advanced IP. A detailed comparison of the latest Arm engagement models can be found here.

Typically, partners license individual components from Arm and pay a license fee upfront before they can access the technology. With Arm Flexible Access they pay a modest fee for immediate access to a broad portfolio of technology, then paying a license fee only when they commit to manufacturing, followed by royalties for each unit shipped. This portfolio includes all the essential Intellectual Property (IP) and tools needed for an SoC design, making it easier to evaluate or prototype with multiple IP blocks before committing to licenses.

IP available through Arm Flexible Access includes the majority of Arm-based processors within the Arm® Cortex®-A, -R and -M families. These CPUs accounted for 75 percent of all Cortex CPU licenses signed over the last two years. It also includes Arm TrustZone and CryptoCell security IP, select Mali GPUs, system IP alongside tools and models for SoC design and early software development. Access to Arm’s global support and training services are also included.

A full list of the Arm IP available through Arm Flexible Access can be found here.
