Battery charging is a complex electrochemical process, in which the discharged electric energy is replenished from the electric power grid. This is accomplished using a battery charger, which is an electrical/electronic device that converts the incoming AC line voltage into a regulated DC voltage to meet the charging needs of the respective battery. In a series of articles we are going to explain this to you.

One abnormal example of high frequency chargers available is the high frequency, high ripple, resonant chargers used by EverExceed. These chargers utilize a high frequency resonant power conversion stage, where a resonant circuit is used to generate high frequency resonant voltage and/or current waveforms (Fig. 3).

Unlike resonant type power converters, where an output filter stage is used to filter out the high frequency resonant voltage or current waveforms to yield a clean DC output voltage, these chargers apply the resonant voltage directly to the battery (i.e. use the battery as a filter). As a result, the output of the charger is a rectified high frequency AC resonant voltage as shown in Fig. 3.
