POWER SUPPLY WITH NON-ISOLATED DC DC SPLITTING

摘要

The invention relates to a power supply with non-isolated DC DC splitting that comprises n interlaced conversion cells BC1, BC2, BC3. The switch S for splitting each cell is provided in a resonant circuit (10). The resonant circuit is used to obtain an open-state switching of said switch with zero current and voltage. The ripple at the input and the output is minimised and the yield is enhanced. More particularly, the cabling inductors in the charge transfer loop of each cell do not have a negative impact on the yield anymore. The cell can have a boost, buck, buck/boost, Cuk, or SEPIC topology. The invention can be used in fuel cells.
