Abstract

This paper proposes a new three-phase (3�) high-frequency ac (HFAC) power distribution architecture for space applications. Advantages of this approach include high-quality HFAC generation with improved THD, load-independent voltage gain, etc. A design procedure for a 10kHz ac power distribution is detailed. Inverter switching frequency is selected around 200 kHz. A systematic method is adopted for selecting the inverter switches based on specific performance parameters and power loss. Considering sine-triangle PWM, the AC-side filter inductor is designed to keep the inductor current ripple within a specified limit. The filter capacitor is also selected based on a ripple criterion. Since the inverter is switched at 200 kHz, the critical considerations for high-frequency PCB layout are also discussed. Finally, the proposed inverter design approach is validated experimentally at 1kW, 30 Vph(peak), 10 kHz 3� HFAC system. © 2023 IEEE.
