Abstract This paper presents a novel three port non-isolated converter based on Zeta converter and SuperBuck converter for space applications. The proposed topology can achieve photovoltaic, load and battery energy flow between each other, and avoid the negative output voltage of the Buck-Boost. Benefit form shared inductor of Zeta and SuperBuck, efficiency can easily be improved. This paper analyses the gain characteristics of each mode and design the control strategy based on competition of transconductance control and the maximum power tracking control strategy. Control strategy is verified by PLECS simulation. Finally, a 400W prototype is built based on TMS320F28335, which realizes the digital control of the topology and verifies the feasibility of the topology.
