Scope
This part of IEC 62024 specifies the test methods for the AC loss of the high frequency inductive components used for DC-to-DC converters, and introduces measuring principles, scope of application and matters needing attention for each method.
Purpose
The high frequency inductive components are one of the important components of a DC-to-DC converter because it stores energy and smoothed current.
High frequency inductive components for DC-to-DC converters are advancing in high current, high frequency, and low loss in accordance with market requirements. International and national standards for measuring AC losses in magnetic components include the IEC 62044 standard series and IEC 63300, which are intended to measure magnetic materials such as cores. Therefore, appropriate metrics for high frequency inductive components are needed.
According to the standard, AC loss of the high frequency inductive components for DC-to-DC converter can be accurately compared. Along with this, it is expected to accelerate further property improvement and promote technological progress and quality improvement.
This issue was proposed at the TC 51 Web International Conference hosted by Japan in October 2021, and the necessity was agreed upon.
