Abstract: Power converters are presented having a precharging resistance and a normally closed precharging switch with a controller to limit inrush current during precharging of a DC bus circuit capacitance while preventing operation of rectifier switching devices until the DC bus voltage reaches a threshold value, and then to open the precharging switch and allow selective operation of the rectifier switching devices, with a second capacitance coupled across a rectifier output to mitigate rectifier output voltage spikes due to common mode currents flowing through a DC link choke, and additional capacitors coupled between positive and negative rectifier output terminals and ground to limit the rectifier output terminal voltages with respect to ground.
