IEC TS 62578:2009 pdfダウンロード。Power electronics systems and equipment – Operation conditions and characteristics of active infeed converter applications 1 Scope This technical specification describes the operation conditions and typical characteristics of Active Infeed Converters (AIC) of all technologies and topologies which can be connected between the electrical power supply system (lines) and a current or voltage stiff d.c.-side and which can convert electrical power (active and reactive) in both directions (generative or regenerative). Applications with AIC are realized together for example with d.c.-sides of adjustable speed Power Drive Systems (PDS), Uninterruptible Power Systems (UPS), active filters, photovoltaic systems, wind turbine...
