Power conversion system and flight vehicle

A power conversion system incorporated in a flight vehicle, the power conversion system comprising:

• a module having a semiconductor element stored therein,
• wherein an energy storage is disposed above the module in a vertical direction, the energy storage storing a solid or liquid energy source containing a neutron attenuating material, and
• wherein at least either the module or the energy storage is provided with a movable mechanism that moves to shift in position according to a tilt of the flight vehicle,
• wherein the movable mechanism includes:
• a first slider rail attached to a lower surface of the energy storage;
• a second slider rail attached to a lower portion of the first slider rail;
• and
• a slider movable unit is attached to a lower portion of the second slider rail, and
• wherein the module is attached to a lower portion of the slider movable unit.
