摘要：A contactor control system comprising a switching member, a high voltage load,a high voltage energy storage, a bi-directional DC/DC-converter operatively connected to
the switching member, a high-voltage capacitor operatively connected to the high-voltage load, and a low voltage energy storage operatively connected to the bi-directional DC/DC-converter, wherein the switching member is adapted to connect anddisconnect the high voltage energy storage to and from the high voltage load, where thebi-directional DC/DC-converter is adapted to pre-charge the high-voltage capacitor to apredefined voltage value from the low voltage energy storage before the switchingmember is closed and adapted to discharge the high-voltage capacitor to the lowvoltage energy storage when the switching member has been opened. The advantage ofthe invention is that a DC-link capacitor can be charged from and discharged to a lowvoltage battery by using a bi-directional DC/DC-converter. Energy losses can thus beminimized.
