Analysis and Control of Multi-Input, Single-Output, Non-Isolated DC/DC Converter for Effective Renewable Energy Management

In this paper a novel multiple-input DC-DC topology achieving fixed output power with 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 results are presented to validate the performance of the topology.
