Outline
The hybrid power supply technology can effectively integrate the advantages of different power supply units, which is one of the key technologies to realize high power density pulse load power supply systems. Aimed at the problems in the existing aerospace servo pulse load power supply system such as a large capacity and a low power density, a battery-active capacitor pulse load hybrid power supply system and the corresponding optimal capacity configuration technology are proposed. First, the system architecture and operation state are analyzed, and the optimization target and key constraints are established. Second, the capacity of the battery and active capacitor are optimized using an analytical method, and the distribution manner of pulse load power between the battery and active capacitor is established, so as to realize the volume minimization of the power supply system. Finally, an experimental prototype of the pulse load power supply system with a constant power of 2.7 kW and a peak power of 35.0 kW was constructed in the laboratory, and experimental results verified the theoretical analysis.
