Balanced Multiphase High Frequency Micro-Distribution Power Bus for electric vehicles (BM-HFMDB)

A Balanced Multiphase High-Frequency Micro-Distribution Bus (BM-HFMDB) for electric vehicles (EV) has the same copper (e.g., wire) utilization as the traditional DC bus but provides convenient compatibility with the major power consuming components of an EV, such as regenerative variable frequency AC electric motor or generator systems, but with fewer electronic stages for direct DC or AC conversion and without DC Link stages that always include bulky, inefficient, and expensive reactive components. Unlike all previously proposed multiphase high frequency distribution buses with replicated circuit topologies of simple isolated single phase or DC high frequency buses that were proven to be uneconomical, the BM-HFMDB economically and safely provides bi-directional multiphase power at any voltage, frequency and phase by appropriately modulating the power to the phase windings of a position-dependent-flux high frequency transformer (PDF-HFT) with simple choppers for sharing the common flux energy between phase windings.
