  • Power converter and pre-charging circuit of same
    Patent number: 9287768
    Abstract: A power converter configured to control an electrical load including a supply DC bus, a bus capacitor, a pre-charging circuit of the bus capacitor provided with a limiting resistor, a switched-mode power supply, and a starter assembly of the switched-mode power supply. The power converter includes a selection mechanism configured to connect the supply DC bus either, in a first state, to the starter assembly of the switched-mode power supply or, in a second state, to the bus capacitor to short circuit the limiting resistor.
    Type: Grant
