The MV converter uses a unique soft charging technology to effectively eliminate excitation inrush current by pre-charging the capacitors in the converter power unit with the control power supply. There is no impact on the upper-level HV switch cabinet, and no impact on the DC capacitor in the power unit, which prolongs the service life and reliability of the capacitor.
