An electric power generating system (EPGS) may comprise a permanent magnet generator (PMG) comprising a rotor comprising a permanent magnet and a stator comprising a first armature winding configured to output a first three-phase voltage, and a second armature winding configured to output a second three-phase voltage. The EPGS may further comprise a passive rectifier configured to rectify the first three-phase voltage, an active rectifier configured to rectify the second three-phase voltage, and an active rectifier controller, wherein the active rectifier is controllable in response to a current reference received by the active rectifier controller. An EPGS may comprise a tunable notch filter configured to filter a first DC voltage and/or a DC output voltage, in accordance with various embodiments.
