    Abstract: According to one embodiment, an inspection system of an embodiment is an inspection system for inspecting a bogie including a plurality of side beams extending in a front-rear direction and disposed apart from each other in a left-right direction and a cross beam connecting the plurality of side beams. The inspection system includes one or more sensors and a position locator. The one or more sensors are installed on at least one of the plurality of side beams and the cross beam and detect elastic waves. The position locator identifies a beam in which the elastic waves have been generated or locates a position of an elastic wave source on the basis of the elastic waves detected by the one or more sensors.

    Abstract: A power generation system in an embodiment includes a power generator, a rectifying and smoothing circuit, a converter, a voltage measurement unit, and a switch. The power generator outputs AC power. The rectifying and smoothing circuit converts the AC power to DC power and smooths the DC power. The voltage measurement unit measures an average voltage of the AC power or a voltage of the smoothed DC power. The converter transforms the smoothed DC power. The switch is disposed between the rectifying and smoothing circuit and the converter, and becomes an ON state when the measured voltage becomes a reference voltage or higher.
