A switched-capacitor interleaved bidirectional converter with wide voltage-gain range for super capacitors in EVs
- Abstract:
- A switched-capacitor interleaved bidirectional (SCIB) dc-dc converter that combines a three-phase interleaved structure with switched-capacitor cells is proposed. The converter features a wide-voltage-gain range, low current ripple on the low voltage side, low voltage stresses across power switches, an absolute common ground between input and output, and can be easily extended into a topology family. The operating principle and power switch voltage and current stresses are analyzed in detail. An 800W prototype with a wide voltage gain range (Uhigh=400V, Ulow=30-100V) is described, demonstrating a maximum efficiency of 95.8% in the step-up mode and 95.9% in the step-down mode.
