Abstract
The auxiliary power supply of marine equipment has multiple power supply level,a large number of cables,and long cable routes,which leads to great difficulty in the selective protection of the system.Using the auxiliary power supply high-voltage power extraction can effectively solve the above problems.Taking the high-voltage-input low-voltage-output DC auxiliary power supply as the research object,aiming at the characteristics of high-voltage-input the high-voltage main power conversion circuit based on three-level half-bridge circuit is designed.In order to realize the self-excited start-up,a high-voltage auxiliary power supply with dual-channel switching of capacitor extraction power and feedback power supply is designed.Finally,a prototype with a rated power of 2 kW is fabricated,and the experimental results verify the feasibility and correctness of the design scheme.关键词
