Abstract
An electric-power conversion apparatus is configured to include: an electric-power conversion circuit in which a positive-side switching element and a negative-side switching element are connected in series and from which an AC output is taken out; a DC voltage detector; a phase current detector; and a control device having a control unit that outputs a control signal and a speed instruction signal, an overvoltage protection unit, an overcurrent protection unit, and a gate driving unit that drives the switching elements on the basis of the control signal and the speed instruction signal and that stops driving the switching elements on the basis of the overvoltage interruption signal and the overcurrent interruption signal, wherein, when the speed instruction signal is changed, at least one of the overvoltage determination threshold value and the overcurrent determination threshold value can be changed simultaneously.
