重庆大学硕士学位论文英文摘要 重庆大学硕士学位论文 英文摘要 PAGE PAGE IV ③ The nonlinear relationship between harmonic resonance frequency of capa citor-filtered single-phase diode bridge rectifier circuit and circuit parameters, was fitted by complete cubic nonlinear regression analysis, and the best regression e quation was carried out. Harmonic resonance frequency can be forecasted in the case of known circuit parameters. The impact on resonance frequency by changin g circuit parameters was studied by using the best regression equation. The resul t indicated that: the resonance frequency is affected more prominent by the chan ging of system reactance and filter-capacitor, and equivalent resistance of load is the secondary sensitive factor.
