High Voltage DC-DC Converter of Pulsed Plasma Thruster for Science and Technology Satellite-2 (STSAT-2)

摘要

Normally, +28V is used to provide the power with a micro satellite, which is generated the solar panel as well as a power regulation unit. However, the pulsed plasma thruster (PPT) requires a high power around +1500V to work for satellite attitude control. Therefore, this paper describes the power processing unit (PPU) for the pulsed plasma thruster by using a flyback switching circuitry as well as a protective circuitry with a feedback control to avoid an over charging.
