The renaissance of fixed resistors in power electronics
The ideal component to limit inrush-currents while charging the bulk-capacitor allows an exact calculation of the maximum inrush- and charging current under all operating conditions. An incomplete charging of the DC-link capacitors can be excluded. The required characteristics are available without delay at all operating conditions. For the application in power electronics with a long lifetime-expectancy it is very robust. In case of failure, the End-of-Life behavior is always Fail-safe and the electronic circuit is disconnected safely from the mains.
