Abstract:
A high voltage battery system can receive power from an AC grid and deliver power to a low voltage battery system. Embodiments can include an active filter and high voltage to low voltage (HVLV) DCDC converter to reduce harmonics associated with the charger reaching the low voltage battery system and further to stabilize the voltage presented to the HVLV DCDC converter to improve its operating efficiency.
