1. A configurational structure of a unidirectional/bidirectional AC/DC power supply, comprising:
a case, being rectangular, containing therein an accommodating space, defining a first direction and a second direction, having a first lateral wall and a second lateral wall extending in the first direction at two laterals thereof, and having a front wall and a back wall extending in the second direction at a front and a back thereof;
a first bus unit, being installed in the case so as to extend in the first direction and be against the first lateral wall, and having one end extending to an outside of the back wall;
a power factor correction (PFC) unit, being installed in the case so as to extend in the second direction and be close to the front wall, and being electrically connected to the first bus unit, wherein the PFC unit is a three-phase three-level power factor correction circuit;
three power module units, being installed in the case so as to extend in the first direction and be in parallel to each other, being located between the PFC unit and the back wall, and being electrically connected to the PFC unit;
a second bus unit, being installed on the back wall so as to extend in the second direction, having one end electrically connected to the power module units, and having an opposite end extending to the outside of the back wall; and
a control system unit, being installed in the case so as to extend in the first direction and be against the second lateral wall, and being electrically connected to the PFC unit and the power module units.
