General Description
The Vanner
High Voltage DC-DC Converter
(commonly referred to as HBA in this document) is an
efficient and highly reliable method of converting high dc voltage present in hybrid drive systems to low dc
voltage (24V) for auxiliary batteries and loads. The converter is designed to be a direct replacement for a
belt driven alternator to increase reliability and reduce maintenance costs.
The converter is J1939 CAN (Controller Area Network) enabled and is fully configurable and controllable
over a J1939 compliant network but is also capable of autonomous operation. The converter is designed
to monitor and report the status of several critical functions and provides real-time fault signals over the
CAN bus to the vehicle electrical system controller.
A typical system includes a high voltage energy source (500
– 780VDC), a Vanner HBA and a low
voltage battery bank for auxiliary loads. The HBA is provisioned with a two pin sealed connector for
integration into the vehicle
’s high voltage interlock system and a fourteen pin sealed circular connector for
CAN and vehicle I/O.
Paralleling:
The outputs of two HBA's may be connected in parallel to double the output capacity of the
24V charging system. Please contact Vanner engineering and/or sales for the appropriate HBA model
number for your dual application.
