Abstract
An integrated multi-port generator-rectifier device includes multiple passive output ports provided from a plurality of passive-rectifier windings on a common, single magnetic structure. The passive-rectifier windings interact with a plurality of magnetic poles. Coils in the passive rectifier windings are serially connected. Each of the passive rectifier windings has a pitch as that is a fraction of magnet pole pitch and a pattern to magnetically decouple back emf phases of the separate rectifiers. The device further includes an active port provided by an active rectifier.

An integrated multi-port generator-rectifier device, comprising:
- multiple passive output ports provided from a plurality of passive-rectifier windings on a common, single magnetic structure, wherein the passive-rectifier windings interact with a plurality of magnetic poles, wherein the passive rectifier windings are serially connected, wherein each of the passive rectifier windings comprises a pitch that is a fraction of magnet pole pitch and a pattern to magnetically decouple back emf phases of the separate rectifiers, the device further comprising an active port provided by an active rectifier.
An integrated multi-port generator-rectifier device, comprising:
- a plurality of ports, wherein one of the plurality of ports powers an active rectifier and the remaining power capacitor-less passive rectifiers, wherein the active rectifier is axially split from the passive rectifiers, wherein the passive rectifiers share a common and single magnetic structure comprising a plurality of magnetic poles, wherein each passive rectifier has a three-phase winding set, and each phase is 120-degree phase shifted from the other two, wherein each phase winding in the three-phase winding set comprises serially connected multiple coils, wherein each coil comprises a pitch that equals a fraction of a magnetic-pole pitch of the magnetic poles;
- wherein a coil connection pattern of the serially connected coils is configured such that each phase winding comprises a zero-average winding function that consists of two non-zero, bi-pole intervals such that any two phases on the passive-port magnetic structure are magnetically decoupled to provide zero mutual inductance.
