DIN EN 61071 VDE 0560-120:2008-01

This International Standard applies to capacitors for power electronics applications. The rated voltage of capacitors covered by this part is limited to 10000 V. The operating frequency of the systems in which these capacitors are used is usually up to 15kHz, 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. This standard covers an extremely wide range of capacitor technologies for numerous applications: overvoltage protection, d.c. and a.c. filtering, switching circuits, d.c. energy storage, auxiliary inverters, etc.
