A power conversion controller for electric train in one aspect of the present disclosure includes an active current command value generator, an overhead line voltage detector, an initial value calculator, an adjustment value calculator, an upper limit value setter, and an output limiter. The output limiter outputs a reactive current command adjustment value calculated by the adjustment value calculator as a reactive current command value when the reactive current command adjustment value is equal to or lower than an upper limit value set by the upper limit value setter, and outputs the upper limit value as the reactive current command value when the reactive current command adjustment value exceeds the upper limit value.
