Design and Real-Time Validation of a Three-Phase Inverter Using an Interleaved Synchronous Super-Lift Luo Converter for Aircraft Power Systems

This paper examines a 24 kVA three-phase inverter supplied by a set of four synchronous Super-Lift Luo DC–DC converters (ISSLLC) connected in parallel to a common DC link. The converters boost a 28 V DC input to approximately 400 V, which then feeds a 115 V, 400 Hz inverter intended for aircraft electrical systems. The overall system was modeled analytically, simulated using PLECS, and validated in real time on a Typhoon HIL platform. In both simulation and HIL, the DC link remained low ripple, and the inverter delivered well-balanced three-phase output voltages. The measured total harmonic distortion was 0.77%, and the power factor was close to unity, staying within MIL-STD-704F limits. The agreement between the simulation and HIL results confirms the precision and real-time feasibility of the proposed ISSLLC-based inverter for aerospace and other high-gain, high-efficiency applications.
