A digital controlled two-stage battery charge system is designed and implemented in this paper. The frontstage of the system is an interleaved boost power factor corrector which is used to reduce input current harmonic distortion and provides stable bus voltage. An isolated fullbridge resonant converter which can provide stable voltage and current to the battery is adopted in the rear-stage. The operating principles of both the power factor corrector and full-bridge resonant converter are discussed in detail. An adaptive frequency modulation method with input voltage ripple feedforward control is adopted to reduce the double-line-frequency ripple.
