Electric propulsion systems comprise the following main components:<br />
- S<strong>to</strong>rage and feed system that s<strong>to</strong>res and feeds the propellant <strong>to</strong> the thrusters <strong>to</strong><br />
generate thrust<br />
- Valves, piping which connects the propellant s<strong>to</strong>rage system with the thruster<br />
- Electric control unit <strong>to</strong> operate electrically the valves and thrusters<br />
- Electric power supply and power processing system<br />
Electric Power Genera<strong>to</strong>r<br />
Energy can be obtained from either sunlight or from a nuclear reac<strong>to</strong>r. In the case of solar<br />
electric propulsion, solar pho<strong>to</strong>ns are converted in<strong>to</strong> electricity by solar cells.
