Abstract
The inverter circuit can be structured by a simple structure as follows: an inductive element (the primary winding) 23 whose one end is connected to a DC power source 21; the first capacitor 24 connected in parallel with it; a serial circuit of the second switching element 27 and the second capacitor 25; a common connection point to which the primary winding 23, the first capacitor 24, and the other end of the serial circuit are connected; and the first switching element 26 to open and close control between the DC power source 21 and the other portion, are provided, and a drive signal generating means (resistance) is connected between the control terminal of the second switching element 27 and the common connection point.
Claims4
An inverter circuit comprising:
- an induction element whose one end is connected to a DC power source;
- a first switching element for controlling a supplement of an electrical power from the DC power source to the induction element;
- a first capacitor for resonance of the induction element;
- a second capacitor for the resonance of the induction element;
- a second switching element connected in series with the second capacitor;
- and
- a drive signal generator whose one end is connected to the first switching element and the second capacitor through a node, the drive signal generator whose other end is connected to a control terminal of the second switching element.
