  • Step-up converter, corresponding inverter and method of operation
    Patent number: 10491103
    Abstract: A step-up converter includes a first inductance electrically connecting a first DC voltage input of the step-up converter to a first junction point, a step-up converter switch connecting the first junction point to a second DC voltage input and a second DC voltage output of the step-up converter, a first diode connecting the first junction point to a first DC voltage output of the step-up converter, and a snubber circuit comprising a charging path and a discharging path. The discharging path runs as a series connection of a capacitor and a second diode from the first junction point to the first DC voltage output, and the charging path is connected at its one end to a junction point between the capacitor and the second diode and is arranged such that the capacitor is charged when the step-up converter switch is switched on.
