Document Type and Number:
Japanese Patent JP2004312966
Kind Code:
A
Abstract:
To provide an inverter device that is simple and low-cost, and that has a large power factor improving effect.
An inductor 92 is provided that belongs to an inductive load 90, and auxiliary winding 920 is provided that interlinks with the main winding of the inductor 92. The auxiliary winding 920 is inserted in a closed circuit including a rectifying power supply 10 and an auxiliary capacitor 20. A current that is formed in the auxiliary winding 920 when the electromagnetic energy of the inductor 92 is discharged passes through the rectifying power supply 10 in the forward direction to charge the auxiliary capacitor 20.
