31 Mar ACT White Paper: High Frequency, High Ripple Resonant Chargers Good or Bad?
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.
High frequency and high ripple resonant chargers exhibit many undesirable characteristics that can cause additional battery heating, reduce charging process effectiveness, and/or interfere with other monitoring devices and sensitive equipment due to the spewing of the high frequency noise via the DC charging cables.
