Abstract
A power conversion apparatus includes a converter having an input power source Vin, a reactor L, a switching element Q, and a rectifying element D, a smoothing capacitor Cconnected to an output terminal of the converter, and a controllerto turn on/off the switching element and thereby control power to be outputted from the converter. The controller has a pulse generatorto generate a pulse signal according to an input voltage to the converter and an output voltage from the converter, the pulse signal being used to turn on/off the switching element. The controller also has an adjusterto mask an ON time of the pulse signal for a predetermined time and thereby provide the pulse signal with an adjusted ON time, the adjusted ON time determining a duty ratio at which the switching element is turned on/off.
