Scope

Scope: This document specifies the technical requirements for the reliability test items, test conditions, and test methods of IGBT modules used in flexible DC transmission. This document is applicable to the production, inspection, and delivery of crimped and welded IGBT modules for flexible DC converter valves and high-voltage DC circuit breakers. Main technical content: This standard applies to IGBT modules used in flexible DC transmission. Other new IGBT devices such as enhanced injection IGBT (IEGT) and dual-mode insulated gate transistors (BIGT) can also refer to this standard. This standard introduces the relevant content of the reliability test specification for IGBT modules used in flexible DC transmission, including the scope of application, definitions of related terms, test items, test procedures, and acceptance criteria. This standard takes into account the special working conditions of IGBT modules used in flexible DC transmission, and provides more targeted and detailed provisions and special requirements for test conditions and procedures. This can effectively solve the problems of long testing cycles, high risks, and high costs in verifying the performance of IGBT modules through actual operation, and provide technical guidance for the reliability test of IGBT modules used in flexible DC transmission. The main contents are as follows: Foreword 1 Scope 2 Normative references 3 Terms and definitions 4 Symbols and abbreviations 5 Test items 6 Test 6.1 Long-time double-pulse test 6.2 Repeated safe working area test 6.3 Diode multi-cycle surge current test 6.4 IGBT saturation zone surge current test 7 Acceptance criteria
