Power Loss Determination Methods for Complete Drive Module Corresponding to International Standards for the Energy Efficiency of Power Drive Systems

Abstract

This paper describes power loss determination methods for complete drive module (CDM) corresponding to international standards for the energy efficiency of power drive systems (PDS). In IEC 61800-9-2, which was published in 2017, two representative methods are specified to determine the power loss in CDM. One is an input-output method, which measures the input power and output power by using a power meter. The other one is a loss calculation method, which calculates the power loss by using a simulation model of CDM. This paper explains the input-output method and proposes a loss calculation method based on the unit test results of power semiconductors and the component data obtained from the manufacturers. The proposed method is validated by comparing its results with the input-output measurement results.
