چکیده
This paper presents the numerical design algorithm for the class-DE amplifier, taking into account optimized resonant inductor designs. The proposed design algorithm provides the element values for satisfying the class-E switching conditions. Simultaneously, the optimal inductors, which have a minimum volume for achieving the permissible power conversion efficiency, can be obtained. By carrying out the circuit experiments, it is shown that the designed class-DE amplifier satisfied zero-voltage switching and zero-derivative switching (ZVS/ZDS) conditions and permissible power conversion efficiency, which verify the proposed algorithm. The experimental results showed the 92.3 % power efficiency for 5.95 W output power by using the Micrometal T80-2 powder toroidal core and the AWG 18 wire.

متن کاملDesign Equations for Class-E Power Amplifiers
In literature, it is widely accepted that the design of Class-E Power Amplifier (PA) with finite dc feed inductance requires a long iterative solution procedure. To avoid such iterative solution methods, analytical design equations should be known. The problem associated with the finite dc feed inductance Class-E PA is usually ascribed to the fact that the circuit element values are transcenden...
