40、LWAY APPLICATIONS ROLLING STOCK EQUIPMENT CAPACITORS FOR POWER ELECTRONICS Part 1: Paper/plastic film capacitors 1 Scope This part of IEC 61881 applies to capacitors for power electronics intended to be used on rolling stock. The rated voltage of capacitors covered by this part is limited to 10 000

41、V. The operating frequency of the systems in which these capacitors are used is usually up to 15 kHz, while the pulse frequencies may be up to 5 to 10 times the operating frequency. It distinguishes between AC and DC capacitors. They are considered as components mounted in enclosures. NOTE This stan
