Trends in Electrical System Design

I was trying to figure out what is happening in the electrical design space in terms of vendor-neutral data format similar to AP242 (STEP/JT) for mechanical engineering. Apparently it doesn't really exits? "The nature of electrical engineering data is often more complex and multifaceted than mechanical geometry. It involves: Logical connectivity, Physical layout, Component parameters, Simulation data, Firmware/Software integration" "1. For PCB Design and ECAD/MCAD Collaboration: - IDF (Intermediate Data Format) => widely used neutral file format for exchanging PCB layout data between ECAD and MCAD. It allows for the exchange of board outline, component placement, holes, and keep-out/keep-in areas. - IDX (Incremental Design Exchange): => a more advanced standard for ECAD/MCAD collaboration than IDF.3 It supports incremental data exchange, meaning only changes are communicated between the ECAD and MCAD environments. 2. For Electrical Schematics and System Design: - XML-based formats: Many systems use XML-based formats for exchanging electrical specifications, device lists, connectivity information, and other data within their own ecosystems or with partners. For example, Dassault Systèmes uses iXF (an XML-based format) for data exchange within CATIA Electrical Tools. - IEC 61970/61968 (Common Information Model - CIM): These international standards are particularly relevant for power system applications (transmission and distribution grids). - CIM defines a common information model for electrical networks, facilitating data exchange between different power system applications. - For Materials and Manufacturing Information: IPC-175x Series: This family of standards (e.g., IPC-1752A for material declarations, IPC-1756 for manufacturing requirements) establishes standard XML-schema based reporting formats for data exchange related to materials and manufacturing requirements in the electronics supply chain."

#Electrification for #aviation and #drones is driving improvements in power electronics density. These areas are providing the demand to continue improving semiconductors and circuit topologies. [1] The best power #electronics today requires less than 1% of the mass and volume of the best power electronics in 1970. In the next decade, power electronics are expected improve even more. Projections estimate that power inverters & converters will half the volume and mass needed today. Also, efficiency is expected to improve with heat rejection dropping up to 75% by 2050. These trends will make it easier to electrify applications with packaging or mass constraints. This includes the demanding requirements in #aerospace and #robotics. The reduction in heat losses, coupled with the expected improvements in motor efficiency [2] suggest that #space robotics will become easier in the future with fewer mass and heat rejection requirements. #deeptech #hardtech #spacetech

Exciting news! I had a chance to speak with Scott Hall from Gaston Electrical, who shared some insights on Digital Electricity. As we move towards the future, Digital Electricity is set to become a game-changer in the field of electrical engineering. Unlike traditional electricity, Digital Electricity has several benefits that make it safer and more efficient. Digital Electricity works by converting AC power into digital signals, which can then be controlled and managed through software. This allows for better control and monitoring of electrical systems, with a safer install. One of the most interesting aspects of Digital Electricity is its ability to interface with Power over Ethernet (PoE). This means that we can power devices like LED lights, security cameras, and VAVs using the same Ethernet cable that provides data to them. Overall, it's fascinating to see how Digital Electricity may transform the electrical industry. With its many benefits and applications, it's clear that we will be seeing more of it in the future. #electricalsafety #electricalcontractor #digitalelectricity#poweroverethernet #massconstructionshow #constructionpodcast#constructionmanagement
