High Frequency Transformer Creepage and Clearance in Compact Converters

Compact converters often place high frequency transformers under pressure from small dimensions, high voltage stress, and strict safety requirements. BaoHui Tech reviews creepage and clearance early because spacing decisions affect insulation reliability, bobbin choice, winding structure, EMI behavior, and manufacturability. Why Safety Spacing Becomes Difficult in Small Designs Creepage is the shortest path along an […]
