Higher short-charge power
Adding a passive compensation winding to a permanent magnet excited homopolar inductor alternator overcomes its power deficiency at short charge times, making it superior to the electrically excited scheme across all charge durations.

Simulation results show that PCW effectively overcomes the short-charge-time disadvantage of PME HIA without PCW compared to EE HIA
The efficiency difference between PME HIA with PCW and without PCW is negligible
PCW resistance should be minimized for high charge efficiency and fast charge speed
