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.
