摘要:A method and an arrangement for charging capacitors of a direct-voltageintermediate circuit of a frequency converter. The arrangement comprises a charging

circuit (CCA) comprising a first diode (D1) and a second diode (D2) connected in serieswith the first diode (D1) and a current-limiting component (AA) connected in parallel withthe series connection of the diodes (D1, D2), whereby said capacitors may be chargedthrough a main switch (K1b, K2b, ..., Knb) of the capacitor, the first diode (D1) and thecurrent-limiting component (AA).
