Non-pulsating Input and Output Transformerless Three-Port DC-DC Converter

In this paper is proposed a non-isolated three-port DC-DC converter (TPC) intended for connection between panel, battery, and load. The proposed converter presents a relatively simple circuit with the use of few components, and low complexity of operation. The proposed topology was analyzed theoretically, and simulated, and a prototype was built in the laboratory to demonstrate the effectiveness of the proposed converter.
