Abstract: Higher requirements are proposed to propulsion for space technology in new environment. As an advanced propulsion technology, electric propulsion has the virtue of high specific impulse, low launching mass and low cost. High voltage power supply is the key technology for high power and high efficiency design, since it is the main power supply for power processing unit (PPU).Application of novel power electronics technology will have a deep effect on geosynchronous orbit,geostationary earth orbit (GEO) telecommunication satellite and deep explanation. This paper focuses on PPU of 5 kW and introduces the current status and development of large power electric propulsion. The characteristics and prospects of large power and high efficiency PPU are analyzed in detail from three aspects of power electronic topology, components and control strategy. It supplies a reference for developing Chinese high voltage power supply of large power PPU.

Key words: spacecraft, electric propulsion, power processing unit (PPU), high voltage power supply, soft switching
