The two sub-modules (22) which are connected in series are provided with single-phase half-bridge on input side and single-phase full-bridge on load side. The full-bridge and half-bridge are arranged parallel to intermediate circuit capacitor. The intermediate circuit capacitor is connected with electric power source (8) of half bridges, when sum of electric power at capacitors are larger than power of power source. The power is discharged from capacitor through electric power source until power at capacitor is reduced to preset voltage lower limit. Independent claims are included for the following: (1) power converter circuit; and (2) electromotor. |
