It is nowadays unthinkable to design a new power electronic device without taking into account the electromagnetic interference (EMI) problems. In this paper, a new type of battery charger is presented with two original points:
- the use of a new kind of multilevel rectifier, which seems very interesting, in spite of its relative complexity,
- the use of a series resonant converter working at the resonance frequency which simplifies the control of this device.
The selected structure is presented after consideration of the advantages and drawbacks of the classical ones and after the presentation of the main solutions allowing for the reduction of the electromagnetic interferences. The different parts of this charger are presented with their particular working. A simple model has been used in order to size each element. Finally, experimental results validate the study.
