The radio frequency ion electric propulsion system is oriented to the application of low-orbit Internet constellations to realize satellite orbit transfer, attitude control, inter-satellite distance control, end-of-life deorbiting and other functions. It is mainly used at orbital altitudes of about 500km. The propulsion system is required to have lightweight, miniaturized, high-efficiency, high-resolution and continuously adjustable performance. Therefore, each individual machine needs to carry out corresponding miniaturized integrated design.
As one of the cores of the RF ion electric propulsion system, the power processing and control unit's main function is to convert the primary bus power supply into the RF and DC power supply modules required for the operation of the RF ion electric propulsion system, and provide system-wide control and data acquisition signals.
The main principle of the radio frequency ion thruster is to apply a certain frequency of radio frequency power to the radio frequency coil wrap
