The constructed topology can realize the energy flow between photovoltaic, load and battery, avoiding the problem of Buck-Boost output negative voltage, and Zeta and Super Buck share double inductors to improve the efficiency. The gain characteristics of each mode are analyzed and the control strategy based on cross-conductance domain control and maximum power tracking control competition is designed. The effectiveness of the control strategy is proved 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.
