Creepage and Clearance guide

The definition of the Creepage and Clearance safety distances required by standards is often neglected in the early stages of electronic design. This, in many cases, leads to late design reiterations, with additional delays and cost. This article serves as general orientation on Creepage and Clearance requirements in transformers and power supplies.

Definition of safety requirements for custom transformers according to EN 61558, EN 61347, etc.

Main requirements related to electric safety depend from specific operational parameters of each SMPS.
Creepage, clearance, insulation thickness and dielectric strength of the transformers are among the most frequent causes of non-compliance by the certification bodies.
ITACOIL is now able to provide a service to define these parameters in compliance with EN 61558 and EN 61347. The preventive definition avoids subsequent changes to the transformer-PCB during final phase of the project, reducing time-to-market and design effort.
The compliance to EN 61558 is frequently required in several product standards like EN 60335, EN 60730, IEC 62115, EN 60065, etc.

QUICK AND EFFECTIVE DESIGN OF HIGH EFFICIENCY LLC CONVERTERS
Standard resonant transformers allow to achieve 96% efficiency of the converter already with the simplest circuit solutions, while further improvements can be made with synchronous rectifiers and other design choises.
Using already tested and developed resonant tanks dramatically decreases design effort for the LLC resonant converter, ensuring immediate success of the project.
The highest level support, also for designing custom resonant transformers, is guaranteed by unique instruments, in addition to the specialization gained in collaboration with the major chips manufacturers.
On the other hand, productions in the LOW-COST area ensure the affordability of high quality products guaranteed by ITACOIL.
