Abstract
The power stage at the output of a high-frequency generates operates in class D and comprises a voltage supply and a common earth, a first and a second switch linked to the common earth and periodically switched on at a high frequency F; these switches are linked to two common-mode inductors connected in a Guanella balun. Each common-mode inductor comprises two inductive lines with strong mutual coupling. The first switch is linked to the input of the first inductive line but not to the second, third and fourth lines and the second switch is linked to the input of the fourth inductive line but not to the first, second and third lines, the output of the first inductive line is linked to an output of the generator, the output of the fourth inductive line is linked to an internal resistor, the inputs of the second and third inductive lines are linked to the supply voltage source, the output of the third inductive line is linked to the output of the first inductive line and the output of the second inductive line is linked to the output of the fourth inductive line.
