Abstract
Passive filters, line replaceable units and a modular power supply are provided. The passive filter comprises an inductor and a diode bridge. The inductor has a first end and a second end. The first end is coupleable to a phase output of an inverter. The diode bridge comprises a first diode and a second diode. The anode of the first diode is coupled to the second end of the inductor and a cathode of the first diode is coupleable to a positive DC bus voltage. The cathode of the second diode is coupled to the second end of the inductor and the anode of the second diode is coupleable to a negative DC bus voltage. The passive filter output is coupleable to cable(s) for an AC electric machine. A reverse recovery charge of the diodes achieves a target DV/DT for an output voltage of the passive filter at operating temperatures.
