Power Processing Unit for Stationary Plasma Thruster
Abstract
Electric Propulsion System consists of Thruster, Power Supply, Feed System etc. ISAC / ISRO has developed HET-50, the Stationary Plasma Thruster (SPT) for this purpose which will be used in North-South station keeping. Fig-1 shows the photo of HET-50 developed by ISRO.To deliver power to the different elements of HET-50, ISRO has designed and developed a Power Processing Unit (PPU). PPU contains different converter modules having isolated outputs with different specifications.PPU is designed to operate from Raw Bus voltage of (30-42.5)V input range and conditions the desired stable power required for HET operation. The continuous input power to PPU package during either HET operation is around 460Watts. The overall PPU mass is around 7Kg.
