Abstract :
New three-level converter topologies are proposed for application of low voltage/high current output DC-DC conversions. The proposed converters operate with small current ripple. Therefore, filter inductor value can be reduced, leading to fast transient response. First, the operation principles of these converters are described. Then inductor design for the converters and control implementation is presented. Computer simulations and experiments verify the basic operation of the new converters.
