Abstract
A power conversion device comprises: power conversion circuitry for converting DC power into AC power and supplying it into a load according to a switching state quantity defined by combinations among switching parameters of switching devices; a voltage output calculation device for calculating a voltage output value on the power conversion circuitry, based on the switching state quantity; an integration value calculation device for acquiring a voltage reference integration value and a voltage output integration value by integrating a voltage reference value and the calculated voltage output value; a switching update-determination unit for outputting an update signal of the switching state quantity, based on the voltage reference integration value, its allowance value, and the voltage output integration value; and a switching determination table for determining a switching state quantity of the switching devices, based on the voltage reference integration value, the voltage output integration value and the update signal.
