Abstract

Abstract

The paper investigates the optimization design of power efficiency of exponential impedance transformer with analytic method and numerical method. In numerical calculation, a sine wave voltage with hypothesis of rising edge equivalence is regarded as the forward-going voltage at input of transformer, and its dominant angular frequency is determined by typical rise-time of actual voltage waveforms. At the same time, dissipative loss in water dielectric is neglected. The numerical results of three typical modes of impedance transformation, viz. linear mode, saturation mode and steep mode, are compared. Pivotal factors which affect the power efficiency of exponential impedance transformer are discussed, and a certain extent quantitative range of intermediate variables and accordance coefficie
- exponential impedance transformer,
- rising edge equivalence,
- power efficiency
