Claim 0:
1. A charger comprising:
a charging interface;
a converter coupled to the charging interface, the converter comprising:
a first plurality of switching transistors coupled to the charging interface,
a transformer comprising a primary winding, a secondary winding, and an auxiliary winding, wherein the primary winding is coupled to the first plurality of switching transistors,
a second plurality of switching transistors coupled between the secondary winding and a battery interface, and
an auxiliary system interface coupled to the auxiliary winding;

a rectifier coupled between the charging interface and the first plurality of switching transistors, comprising an intermediate bus capacitor coupled to the first plurality of switching transistors; and
a controller configured to control the first plurality of switching transistors and the second plurality of switching transistors to generate a first signal at the battery interface and a second signal at the auxiliary system interface;
wherein the converter comprises:
a primary bus capacitor coupled between the second plurality of switching transistors and the battery interface; and
an auxiliary bus capacitor coupled between auxiliary winding and the auxiliary system interface.
