Abstract: High-power electric actuators are generally used on solid propellant motors, which further enhances the requirement on onboard supply voltage and output power of a launch vehicle. In this paper, combined with the electrical demand of China’s new generation solid-liquid bundled launch vehicle (LM-6A), high-voltage battery technology, high-power switch control technology, insulation protection technology under low pressure are studied, and the key technologies and schemes are presented. The flight test of LM-6A shows that the high-voltage power supply and distribution technology adopted is reasonable and feasible, and can be used as a reference for the designs of other launch vehicles or spacecrafts.
