Abstract
An electric power conversion device is a device for supplying an output voltage to a load from output terminals, and includes a rectifier circuit to rectify an AC voltage and to output the rectified voltage, a booster circuit to supply the output voltage to the output terminals, a voltage detector to output a voltage detection value indicating the output voltage, and a controller. The booster circuit includes a reactor connected to the rectifier circuit, a smoothing capacitor to smooth the rectified voltage, thereby generating the output voltage, and a switching element to short-circuit the reactor. The controller controls a conduction period of the switching element based on the voltage detection value so that a first pulsation frequency which is a frequency of pulsation of the output voltage is higher than a second pulsation frequency which is a frequency of pulsation of the rectified voltage.
