• Diode-capacitor voltage multiplier stages
• high-voltage-gain dc-dc power electronic converters

A family of nonisolated high-voltage-gain dc-dc power electronic converters is proposed. The suggested topologies can be used as multiport converters and draw continuous current from two input sources. They can also draw continuous current from a single source in an interleaved manner. This versatility makes them appealing in renewable applications such as solar farms. The proposed converters can easily achieve a gain of 20 while benefiting from a continuous input current. Such a converter can individually link a PV panel to a 400-V dc bus. The design and component selection procedures are presented. A 400-W prototype of the proposed converter with V-in = 20 and V-out = 400 V has been developed to validate the analytical results.
