Abstract :
A novel frequency domain modeling of a series resonant DC/DC converter in continuous-current mode is presented. The method is general and can be applied to study the performance of the converter for both variable frequency and pulse width modulation control techniques. Generalized curves for voltage gain Eo/Ei and phase-shift phi are provided. It is shown that once the values of Eo/Ei and phi are known, steady-state performance of the converter can easily be obtained by using nth harmonic equivalent circuits.<>
