Power Electronics PCB Design Extended Edition: Professional Guide to High-Current, Thermal Management, Power Conversion, EMI/EMC, and Reliable PCB Engineering (PCB Engineering Mastery Series)

Power Electronics PCB Design — Practical Guide to High-Current, Thermal, and Power Conversion PCB Engineering

Designing a power electronics PCB requires much more than connecting components according to a schematic. At high current and fast switching speeds, the PCB becomes an active part of the power-conversion system. Copper geometry, current paths, parasitic inductance, thermal behavior, grounding, switching nodes, and isolation directly affect efficiency, EMI, temperature, safety, and reliability.

This Extended Paperback Edition provides a practical approach to professional PCB design for power converters, battery systems, motor drives, industrial electronics, and other high-power applications.

While the ebook offers a concise introduction and quick reference, this expanded edition develops the subject in greater depth, connecting PCB layout, thermal management, EMC, safety, manufacturing, measurement, debugging, and failure analysis into a complete engineering workflow.

The book begins with power-conversion architectures and the fundamentals of current, resistance, voltage drop, and power dissipation. It then explores copper thickness, high-current traces, power planes, vias, connectors, current density, and electrical bottlenecks, focusing on the complete power path.

Dedicated chapters examine thermal engineering, including heat flow through packages, copper, thermal vias, internal planes, thermal interface materials, heatsinks, chassis structures, and ambient.

The switching-power section covers practical layout techniques for buck, boost, buck-boost, half-bridge, and full-bridge converters, together with MOSFET gate drivers, Kelvin-source connections, GaN and SiC devices, magnetics, high-di/dt loops, high-dv/dt switching nodes, parasitic inductance, ringing, overshoot, and snubber design.

EMC topics include conducted and radiated emissions, common-mode and differential-mode noise, return-current control, filters, shielding, chassis connections, and EMC-oriented PCB partitioning.

The extended edition also covers multilayer stackups, heavy-copper engineering, high-voltage design, creepage, clearance, isolation, DFM, DFA, and manufacturing reliability.

The final chapters move from design to real hardware, with guidance for safe prototype bring-up, electrical measurements, thermal and EMI debugging, failure analysis, and root-cause identification.

Practical case studies include a 12 V to 5 V high-current buck converter, a high-current Battery Management System PCB, and a thermal/EMI PCB redesign, showing how electrical, thermal, electromagnetic, and manufacturing decisions interact.

Key topics include:

• High-current routing, copper sizing, planes, vias, and connectors
• Current density, voltage drop, and power losses
• Thermal management and thermal via design
• MOSFET, GaN, and SiC layout
• Buck, boost, buck-boost, and bridge converters
• Gate-driver and Kelvin-source routing
• Grounding and return-current control
• Conducted and radiated EMI
• Common-mode and differential-mode noise
• High-voltage design, creepage, clearance, and isolation
• DFM, DFA, and production reliability
• Safe bring-up, measurements, and debugging
• Failure analysis and practical case studies

Written for PCB designers, electronics engineers, hardware engineers, power electronics engineers, advanced students, and professional developers, this book focuses on the physical engineering decisions that determine whether a power converter performs reliably outside the schematic.

A practical engineering reference for designing power PCBs as complete electrical, thermal, electromagnetic, safe, and manufacturable systems.
