INVERTER DEVICE

PROBLEM TO BE SOLVED: To provide an inverter device which can easily prevent generation of flickers in a light emission device even when the light emission level of the device is lowered. SOLUTION: The inverter device includes: a rectifier 2 which performs full-wave rectification of an AC power source 1; a switching device 3 which switches a pulsating flow having a half cycle of an AC power source subjected to the full-wave rectification by the rectifier 2; a transformer 4 having a primary side to which the high frequency obtained by the switching device 3 is input and a secondary side from which boosted AC is output as a supply power to a light emission device 6; and a control device which controls the current of the supply power by the pulse width of the switching ON signal to the switching device 3. The control device transmits two or more ON signals to the switching device 3 in one cycle of the pulsating flow. COPYRIGHT: (C)2010,JPO&INPIT
