Switching power circuit, and lighting device for semiconductor light-emitting element and illumination apparatus using same |
摘要 |
A switching power circuit includes a first switching element having one end connected to a positive electrode of a first capacitor, a second switching element having one end connected to a negative electrode of the first capacitor, an inductive element having one end connected to the other ends of the first and the second switching element, a semiconductor switching element connected in parallel to the current limiting resistor, and a second capacitor connected to a control electrode of the semiconductor switching element. The second capacitor is charged by using a voltage induced to the inductive element when the first or the second switching element is off.
