This thread will document my EV charger design & build. Since my high performance drive for induction motor operates on 144Vdc I figured I would need a custom designed EV charger as well to match the voltage level.
At this moment in time I am not planning on bi-directional operation, this design is for charge mode only.
6.6kW, 144V EV Charger, Concept Topology:
Front End: 2-phase interleaved power factor correction with voltage boost pre-regulator
Power Supply: Phase shifted full bridge with zero voltage switching and galvanically isolated output by means of a transformer
Link to High Performance Drive for 3-phase AC Induction Motor, which is still in DRAFT state: http://ivanbennett.com/forum/index.php?topic=112.0
