This paper describes the analysis following the breakdown of an ion cyclotron radio frequency (ICRF) tuner purchased from Advanced Ferrite Technology (AFT). The codes used in the analysis were CST and COMSOL. These codes use the standard gyromagnetic model for the ferrite, which gives results that are largely in error when compared with measurements at ICRF and at lower hybrid frequencies. We have...
This paper describes the analysis following the breakdown of an ICRF tuner purchased from AFT. The codes used in the analysis were CST and COMSOL. These codes use the standard gyromagnetic model for the ferrite which gives results that are largely in error when compared to measurements at ICRF and Lower Hybrid frequencies. We have measured a slab of the ferrite used in the ICRF tuner provided by AFT...
This paper introduces an optimization based approach towards steady-state analysis of switched power electronic systems. The convergence performance of the optimization is improved by the estimation of the state variables in steady-state. Accurate state variable estimation can be achieved by previously simulating a set of multi-resolution approximations - averaged models of the original topological...
