Design 72V-12V Automotive DC-DC

@macroenergy

With an extensive background in electrical engineering and electronics, I believe I have the skills and experience required to design this high-powered DC-DC converter for your automotive EV platform. My detailed knowledge of power electronics and PCB design, specifically with Altium, prepares me to maximize the efficiency of the schematic capture and optimize the thermal paths efficiently. Moreover, my experience in designing critical analog systems aligns with the stringent requirements of this project. I have worked on projects that required clean, noiseless signals within precise thresholds such as your 12 V ± 5 % output requirement. With my robust grasp on Orcad simulation, we can ensure our solution is stable even under rapid load swings and other potential sources of EMI. Additionally, my expertise in Matlab will ease conducting thermal analysis and calculations for designing an enclosure that handles temperature extremes. Lastly, my previous work in renewable energy has always pushed me to deliver 'automotive-grade' standards, including designing reliable electronics capable of handling wide input transients. My commitment to efficiency through all stages – be it control loop stability, EMI strategy or beta testing – matches your desire for an optimized yet sturdy unit. I look forward to working with you and contributing my skills towards developing a world-class electric mobility solution.

Hi there, I carefully read your project, and I can help design a compact isolated DC-DC converter for your EV platform, delivering a clean 12V / 20A rail from a 38–72V traction battery with high efficiency, strong protection, and automotive-grade reliability. I’m Samuel Tshibangu, a mechatronics engineer with strong experience in power electronics, PCB design, thermal-aware layouts, EMI filtering, and high-current DC systems. I’ve worked with similar converter architectures, automotive voltage environments, protection circuits, and compact power boards, so I can move quickly and deliver a reliable manufacturable design. For this project, I would propose an isolated forward, push-pull, or half-bridge topology depending on final size, cost, and efficiency targets, with properly designed magnetics, synchronous rectification where suitable, robust input filtering, OVP/OCP/thermal protection, and a PCB layout optimized for heatsink mounting and low EMI. I can deliver the schematic, PCB layout, Gerbers, BOM, thermal calculations, and design notes covering control loop stability, EMI strategy, and validation. Feel free to send me a message. Best regards, Samuel Tshibangu

Hello, I can design a compact, automotive-grade isolated DC-DC converter for your EV platform. I’ll use an efficient LLC or PSFB topology to achieve >90% efficiency, stable 12V output (2–20A), and strong performance under fast load changes. The design will include full protections (OVP, OCP, OTP), input surge/load-dump handling, and EMI-aware layout. PCB will be optimized for thermal performance and direct mounting to your metal enclosure. Deliverables: Schematic, PCB + Gerbers, BOM with alternates, thermal calculations, and design notes. Ready to start immediately and deliver first schematic for review. Best regards, Mahmoud Ibrahim

Hi, This aligns well with my experience in high-power DC-DC and automotive-grade designs. I would approach this using a robust isolated topology (LLC or phase-shifted full bridge depending on constraints), optimized for >90% efficiency across your load range. Special focus will be on magnetics design, thermal paths to the enclosure, and stable regulation under fast load transients. The PCB will be compact with proper current handling, EMI filtering, and isolation clearances suitable for automotive environments (load dump, surges, vibration). Deliverables include full schematic, optimized layout + fabrication files, BOM with alternates, and thermal + efficiency analysis, along with a concise design note covering control loop and EMI strategy. Happy to discuss topology choice and constraints before starting. Best regards, Ahmed

Hi there, I read your requirements carefully, and I can design the isolated 72V-to-12V automotive DC-DC converter for your EV scooter/e-rickshaw platform with strong focus on efficiency, thermal performance, EMI control, and protection. I will prepare the complete schematic, compact PCB layout, Gerber/drill files, annotated BOM, thermal calculations, and a short design note covering topology, magnetics, control-loop stability, EMI filtering, OVP/OCP, surge protection, and validation tests. For this 12V 20A output, I would use a suitable isolated topology such as half-bridge/LLC or forward converter depending on size, efficiency, and manufacturability. I’ll make sure the design targets ≥90% efficiency, stable 12V regulation under load swings, and automotive-grade reliability for vibration and temperature conditions. Cost: ₹10,000 || Timeline: 3–5 days Best regards,

Hi I can design a compact, automotive-grade isolated DC-DC converter for your 38–72 V traction system, delivering a clean and stable 12 V / 20 A output with >90% efficiency. My focus will be on reliability under real-world conditions—handling wide input transients, fast load changes, and thermal constraints—while ensuring the PCB fits seamlessly into your metal enclosure with efficient heat dissipation. The design will include full protection features (OVP, OCP, SCP, thermal shutdown) and robust EMI filtering aligned with automotive expectations. I have experience developing high-current, space-constrained power electronics with strong emphasis on efficiency, thermal performance, and manufacturability. **Deliverables:** • Complete schematic (Eagle/KiCad ) • Optimized PCB layout + Gerber/Drill files • Annotated BOM with alternates • Thermal calculations at full load • Concise design note (stability, EMI, validation) The final design will meet your requirements of ≥90% efficiency and stable 12 V output (±5%) across 2–20 A load range, ready for manufacturing and validation.

Hi, I have solid experience designing high-power DC-DC converters for automotive/industrial use and can deliver a compact, efficient, and production-ready solution for your platform. Proposed approach: I’ll use an isolated topology suited for 38–72 V input such as phase-shifted full-bridge or LLC resonant (selected after requirement review) to achieve >90% efficiency and low EMI. The design will include synchronous rectification, robust feedback control, and fast transient response for 2–20 A load swings. Power & protection: I’ll design a wide-input front end with TVS, LC filtering, and surge/load-dump protection. Full protection suite: OVP, OCP, thermal shutdown, and soft-start. Control loop will be tuned for stability and fast recovery. Magnetics & thermal: Custom transformer design with proper core selection, winding strategy, and isolation. PCB will be optimized for thermal paths, copper thickness, and direct coupling to your metal enclosure (heatsink). I’ll include thermal calculations for 20 A continuous load. Layout & EMI: Tight high-current loops, proper grounding, shielding, and filter design to ensure low noise and stable operation in automotive conditions. Deliverables: Schematic, PCB + Gerbers, BOM with alternates, thermal analysis, and design note covering control, EMI, and validation. I can start immediately and deliver first schematic quickly for review.
