Abstract

This paper presents a dynamic operation profile emulation method for capacitors used in high-power converters. It preserves the advantages of a recently reported method with a minimum required power supply and is robust to testing sample degradation. This method is suitable for application-oriented stress emulation testing with different types of DC / AC capacitors and multi-condition operation in high power converter systems, such as wind power and railway systems. The circuit architecture and testing ability of this method are presented. Taking the mission profile of the AC capacitors in a railway traction system as an example, proof-of-concept experimental results are presented to verify the feasibility of the proposed test method.
