High-Voltage Rectifier Diodes: Insulation, Electric-Field Control and Series Stacks
At high voltage, the diode rating is only one part of the insulation system. PCB creepage, air clearance, contamination, humidity, altitude, field concentration, potting materials, and measurement technique can become the actual failure limit. This guide focuses on preventing puncture, surface tracking, corona, and partial-discharge damage in high-voltage rectifiers and series stacks. It explains why … Read more
