The invention belongs to the field of helicopter power supply system design, and discloses a helicopter power supply system voltage stabilizing device in a high-power power supply state. The voltage stabilizing device comprises a main bus bar and an electric load bus bar; an isolation branch and a boost branch which are connected in parallel between the main bus bar and the electric load bus bar;a starting motor which is connected to the main bus bar and the power supply which is connected to the main bus bar. The problem that airborne electric equipment cannot work normally due to low voltage of a power grid when a helicopter motor drives an engine to rotate can be effectively solved. 本发明属于直升机电源系统设计领域，公开了一种直升机大功率供电状态下电源系统稳压装置，所述稳压装置包括：主汇流条、用电负载汇流条；并联在主汇流条、用电负载汇流条之间的隔离支路和升压支路；以及连接在主汇流条上的起动电机，连接在主汇流条上的电源；可有效解决直升机电动机带转发动机时，电网低压导致机载用电设备无法正常工作问题。
