“…Therefore, the DSEG-DF can solve the problem of an asymmetric three-phase magnetic circuit inherent in the DSEG with concentrated field windings (DSEG-CF). However, the DSEG-CF performs better than the DSEG-DF with regard to electromagnetic vibration due to the thicker yoke and higher-order spatial EMF harmonics [12]. Therefore, the DSEG-DF does not improve the three-phase unbalance without affecting the performance.…”

The doubly salient electromagnetic generator (DSEG) has the advantages of flexible control, high robustness, and low cost. Since multiple stator poles share a common set of field windings, the magnetic circuit of each phase is asymmetrical, which limits the output performance of the DSEG. The three-phase current balance control for the DSEG system was proposed. By investigating the current waveform under the angular position control (APC), a three-phase current prediction method was proposed. The conduction angle of the power switches in the active rectifier was predicted to make the three-phase current balanced. Based on the analysis and experiment, the current waveform was further analyzed, and the effectiveness of the three-phase current balance control was verified. Compared with the APC method, the output power capacity was improved using the three-phase current balance control under a limited winding current density. The maximum potential of the DSEG was explored, and the electromagnetic load capacity of the DSEG was fully released.
