    High Power PCB Design: Pushing the Limits with Caleb Buck

    Caleb Buck, a PCB Design Electronics Engineer at Nidec Aerospace, discusses the complexities of high-power PCB design, ranging from guitar pedal prototypes to aerospace systems handling over 500 amps. He explains how uneven current distribution in parallel switching circuits can cause connectors to melt due to impedance mismatches, emphasizing the need for symmetrical layout. Buck also details the importance of voltage isolation standards like IPC 2221 Revision C and IPC 2152, material selection for thermal reliability, and the pitfalls of conformal coating on high-power components.

    379: Monstrous Cable Corporation

    Tom Anderson, an engineer at Keysight Technologies, discusses the practical realities of embedded hardware for new college graduates, focusing on the nuances of floating I/O pins, tri-state outputs, and latch-up failure modes. He explains the behavior of inductors in switching power supplies and relays, the importance of pull-up/pull-down resistors, and the differences between ADC types, sampling rates, and bandwidth. Anderson advocates for learning from vintage technical literature, such as TubeBooks.org and 'The Art of Electronics,' and shares his methodology for analog circuit design using symbolic algebra and system-level constraints.

    High Current PDN Design: Engineer of the Year Reveals Industry Secrets

    Ben Dannan, founder of Signal Edge Solutions and DesignCon's Engineer of the Year, discusses the engineering challenges of designing 2,000-amp power distribution networks (PDN) for high-power AI processors like NVIDIA's Blackwell platform. He details the industry's struggle with current densities exceeding 100 amps per square centimeter and the debate between vertical and horizontal power delivery architectures. Dannan also highlights the critical issue of inaccurate silicon models provided by vendors, which often lead to hardware overheating, and introduces his upcoming measurement-based model library for large-signal simulation.

    Reducing Energy Consumed By Household Appliances

    Darrel Kingham, CEO of Cambridge-based startup Pulsiv, explains how their patented power electronics technology eliminates the need for PFC inductors in AC-to-DC conversion, thereby improving efficiency and reducing global energy waste. The technology achieves a flat efficiency profile across variable loads, making it particularly suitable for applications like dimmable LED lighting, data centers, and consumer electronics that spend significant time in standby or low-power modes. Kingham highlights that the solution also eliminates in-rush current, simplifying infrastructure requirements and reducing component costs by allowing designers to use simpler flyback topologies up to 180 watts instead of more complex LLC designs. The company is currently targeting the 250-watt range with reference designs to help manufacturers meet regulations like Energy Star and CEC at the lowest cost, while planning to expand into 600-watt and kilowatt ranges for EV charging using wide bandgap semiconductors.
