Abstract

See full text

An object of the present invention is to provide an inverter device that can readily prevent flickering on a light emitting apparatus even when the light emission level thereof lowers. To achieve the object, an inverter device according to the present invention includes a rectifier (2) that performs full-wave rectification on AC power (1), a switcher (3) that switches pulsating power having a cycle that is one-half the cycle of the AC power having undergone the full-wave rectification in the rectifier (2), a transformer (4) having a primary side to which the high-frequency power provided by the switcher (3) is inputted and a secondary side from which boosted AC power is outputted as supplied power to a light emitting apparatus (6), and a controller that controls the current of the supplied power by using the pulse width of an ON signal that activates the switching and is sent to the switcher (3). The controller transmits the ON signal to the switcher (3) at least twice in a single cycle of the pulsating power.
