Power conversion device

A power conversion device comprising:

• an element unit including a plurality of switching elements, a plurality of diodes, a first positive electrode bus, a first negative electrode bus, and a first outer frame member, the plurality of switching elements being electrically connected to each other in series, the plurality of diodes being electrically connected in inverse parallel to the plurality of switching elements, respectively, the first positive electrode bus being electrically connected to a switching element located at a first end in an electrical connection relationship among the plurality of switching elements, the first negative electrode bus being electrically connected to a switching element located at a second end on a side opposite to the first end in the electrical connection relationship among the plurality of switching elements, the first outer frame member accommodating the plurality of switching elements, the plurality of diodes, the first positive electrode bus, and the first negative electrode bus;
• and
• a capacitor unit including a plurality of capacitors, a second positive electrode bus, a second negative electrode bus, and a second outer frame member, the second positive electrode bus being electrically connected to at least one capacitor included in the plurality of capacitors, the second negative electrode bus being electrically connected to at least one capacitor included in the plurality of capacitors, the second outer frame member accommodating the plurality of capacitors, the second positive electrode bus, and the second negative electrode bus,
• wherein
• the first outer frame member and the second outer frame member are separable from each other,
• the first positive electrode bus and the second positive electrode bus are removably connected, and
• the first negative electrode bus and the second negative electrode bus are removably connected.
