Abstract: An inrush current limiter circuit for a rectifier provides a flow of a current between a rectifying part of the rectifier and a filter capacitance. A power stage includes a power stage resistor and a power stage transistor disposed in parallel circuit arrangement to the power stage resistor. The power stage resistor conducts an amount of the current in dependence on the state of the power stage transistor, and the power stage transistor conducts an amount of the current in dependence on a charging of a gate capacitance of the power stage transistor.

Abstract: A system for controlling an inductor freewheeling voltage includes first and second switches, a first diode, and an inductor. When open, the first switch connects a first terminal of the inductor with a power bus. The first switch is controlled by a first control signal. A first terminal of the first diode is connected to a ground, and a second terminal of the first diode is connected to the first terminal of the inductor. The first diode allows an electric current to pass from the ground to the first terminal of the inductor. When open, the second switch connects a second terminal of the inductor with the ground. A switch control circuit is controlled with a second control signal and keeps the second switch open or such that there is a voltage drop across the second switch.
