<P>PROBLEM TO BE SOLVED: To provide an inverter device in which an auxiliary capacitor is used as a vibrating capacitor by attaching an inductor/an auxiliary capacitor to a smoothing capacitor, in which its rapid discharging increases a feeding effect to a rectifying power supply, and whose power factor is enhanced more than that of a conventional system. <P>SOLUTION: This inverter device is provided with a rectifying power supply 10 that rectifies the voltage of an AC power source 11, the smoothing capacitor 10 that is arranged at its post stage, and an inverter circuit 100 that is driven by receiving the voltage of the smoothing capacitor to form a high frequency voltage. The inverter circuit 100 has characteristics that an input current flows intermittently. The main winding of the inductor 30 is connected in series to the smoothing capacitor 20, and an auxiliary winding 32 is provided that magnetically interlinks with the main winding 31. The inductor 30 accumulates electromagnetic energy via the auxiliary winding 32 when a smoothing capacitor 40 is discharged. The auxiliary winding 32 forms a current I321 that passes through the rectifying power supply 10 in the forward direction when the electromagnetic energy is discharged. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
