Summary:
Class E amplifier, which is a power amplifier with switching characteristics, is known to be efficient in conversion. However, since the switching conditions must be satisfied on the steady state, determining the values of the circuit elements included is difficult. The PSO algorithm has been applied to the optimization problem. However, the high-Q nature prevents the PSO from determining the optimum values efficiently. On the other hand, the computation with respect to a particle is almost independent to the others. Namely, the positions and velocities of the particles can be calculated in parallel. We take advantage of this feature and develop the program suitable for current multi-core processor using OpenMP, which is an API for multi-platform shared-memory parallel programming. It is confirmed that the proposed method accelerates the PSO.
