Design of class-E amplifier using particle swarm optimization <Abstract> Class E amplifier is known as a switching type power amplifier which has a high efficiency and output power. However, he design is very difficult, since the constraints on the steady-state must be satisfied. In this paper , an optimization procedure of class E amplifier proposed, where the particle swarm optimization is used. In the proposed approach, the design parameters or the optimal solution is evaluated by a standard commercial circuit simulator. Therefore, we can determine the parameters considering the nonlinear characteristic of MOSFET included in the circuit fully. We define a new cost function for determining the design parameters of class E amplifier. by the simulation, it is confirmed that the adjusted circuit behaves as a class E amplifier certainly. |
