  • Power converter comprising at least one normally-on transistor
    Patent number: 11728720
    Abstract: The present invention concerns a power converter including: a capacitor (CBUS) having first and second electrodes respectively coupled to first (E1) and second (E2) input terminals via a current-limiting element (R1, L1); at least one normally-on transistor (K1, K2, K3, K4, K5, K6); a circuit (170) for powering a circuit (CMD_K1, CMD_K2) for controlling the normally-on transistor; and a switch configurable to, in a first configuration, couple first (g) and second (h) input terminals of the power supply circuit (170) respectively to the first (E1) and second (E2) input terminals of the converter, upstream of the current-limiting element (R1, l1) and, in a second configuration, connect the first (g) and second (h) input terminals of the power supply circuit (170) respectively to the first and second electrodes of the capacitor, downstream of the current-limiting element (R1, L1).
