Topology Selection and Control Strategy for High-voltage Traction Battery Charger[J]. Electric Drive for Locomotives, 2012,(6):34-36. DOI: 10.13890/j.issn.1000-128x.2012.06.033.
An input-series and output-paralleled (ISOP) circuit topology was very suitable for high input voltage to DC-DC conversion application. Relationship between the voltage sharing and the current sharing of ISOP topology was analyzed, which was concluded that the key question of ISOP topology was to ensure the voltage sharing of the input divided capacitors of each module. A kind of double voltage loop control strategy was studied for the battery power supply unit, which was verified by actual products.
