Originally published at: What Kind of PCBs Power EVs? | Sierra Circuits
Electric vehicles (EVs) use HDI, heavy copper, and insulated metal substrate (IMS) PCBs to support core operations such as battery management and power conversion. Designing these boards presents challenges such as managing thermal stress generated by high-power circuits and minimizing EMI caused by switching systems. In this article, you’ll learn about the different types of printed boards used in EV subsystems, the common challenges involved in designing them, and the solutions to overcome these issues. Highlights: EV power electronics widely utilize heavy copper PCBs to enable high-current handling and reliable operation in traction inverters, DC-DC converters, and battery management systems…
