Claim 17:
18. A multi-function onboard battery charger module (OBCM), comprising:
a boost converter operable to boost a charging input to a boosted output;
an isolation converter operable to electrically isolate the boost converter from the battery pack and to transform the boosted output to an isolated output;
an output filter operable to mitigate noise within an output resulting from one of the boosted output and the isolated output;
an isolation bypass circuit operable between an isolation bypass state and an isolation connect state, the isolation bypass state connecting the boosted output to a filter input of the output filter in bypass of the isolation converter, the isolation connect state connecting the boosted output to an isolation input of the isolation converter; and
a battery bypass circuit operable between a connect state and a disconnect state, the connect state connecting the charging input through a direct connection to an output in bypass of the boost and isolation converters, the disconnect state disconnecting the direct connection.
