Abstract
A voltage control device that controls an output voltage by turning on/off a switching element by a control pulse, the voltage control device including a modulation wave generation unit that generates a sinusoidal wave based on a driving voltage and a driving frequency as a modulation wave, an arithmetic unit that calculates, at any discrete time point [t], a moving average value of a voltage [v] output every time duration [δ] smaller than a time cycle of the modulation wave in a time period [t−Nδ to t−δ] tracing back N (a positive integer) steps from the discrete time point [t] in accordance with Expression (1) below, and a control pulse generation unit that generates the control pulse in accordance with a result of a comparison between the moving average value and an instantaneous value of the modulation wave at the discrete time point [t].
