| 摘要 |
The purpose of this invention is to provide a power-supply device that allows stable resonant operation with an improved power factor. This power-supply device (10), which outputs an AC voltage to a capacitive load, namely a plasma-generating device (5), has an architecture in which a secondary-side excitation inductance in a transformer (4) in this power-supply device (10) is more than five times the magnitude of a leakage inductance. |
