Design and Control of Non-isolated, Multi-input DC/DC Converter for Effective Energy Management

In this paper, a novel multi-input single-output DC-DC converter topology for achieving fixed output power for variable input sources is proposed. The proposed topology consists of conventional boost and buck converters. Effective energy management strategy is used to provide energy to the load, if one of the input sources fails to operate. The converter benefits from several advantages such as minimal operation modes, no limitation for switching duty cycle and fewer components for the size and cost of the converter. Simple control system is introduced by using voltage and current control. Simulation and experimental results are presented to validate the performance of the topology.
