Abstract：A set of dual-input bi-direction pulsating voltage source cells are proposed, and dual-input three-phase aeronautical static inverter topologies are further presented. The topology family has no risk of short-through in bridge, can work in four quadrants, and realizes five-level output within one voltage cycle, effectively reducing harmonic distortion. The configuration mechanism, operation modes of new topologies in four quadrants are analyzed in detail, and the adaptive carrier-based modulation strategy applicable for the topologies is shown in this paper. Then, the mathematical expressions and the transfer function based on the small-signal models are derived. Also, the voltage-current dual-loop control method, the parameters design, and the dynamic response are discussed in the paper. Consequently, experimental results show that the dual-input bi-directional pulsating voltage source cells and topology family are feasible and correct, verify that the modulation method, transfer function and parameter designs are reasonable, and demonstrate that dynamic performance while load changing is acceptable.
