Abstract: An exemplary method for charging a capacitance connected between DC poles of a three-phase active rectifier/inverter and a converter apparatus including a three-phase active rectifier/inverter having a capacitance connected between DC poles thereof, a three-phase filter and a three-phase step-down transformer. The active rectifier/inverter is configured to charge the capacitance connected between the DC poles of the active rectifier/inverter with a rectified secondary voltage of the transformer until a voltage of the capacitance reaches a first predetermined threshold voltage. In response to the voltage of the capacitance connected between the DC poles of the active rectifier/inverter reaching the first predetermined threshold voltage, the active/rectifier/inverter is configured to charge the capacitance with a boosted rectified secondary voltage of the transformer until the voltage of the capacitance reaches a second predetermined threshold voltage higher than the first predetermined threshold voltage.
