Delphi LogoThe Delphi™ DC-DC converter gives you extreme performance and highly efficient power when and where you need it. The manufactured 2.2kW unit creates DC voltages in hybrid and electric vehicles necessary to power 12VDC based components. Liquid-cooled, the DC/DC converter operates at input voltages from 216 to 422VDC with a bi-directional power range max 2.2kW.

Easy, Basic Installation

The Delphi™ DC-DC converter uses standard buck converter technology, it will efficiently convert power from a high-voltage DC source (typically a 300V battery pack) into 14V power. The unique feature is its ability to run the converter backwards as a boost converter to provide low current charging (2.35 amps maximum) to the high-voltage source/battery pack from the 14V supply.

Electrical interface to the vehicle is very simple. The internal controller derives its internal power from the vehicle 14V battery only. The DC-DC converter uses a switching power supply to produce regulated 5V and 12V power. Aside from a discrete IGN hardware (wake-up input) and the high power outputs, all other interface to and from the DC-DC converter is through high speed CAN. The DC-DC will wake up with IGN but requires enabling CAN messages before normal operation can occur. Once normally operating, the production of 14V power is independent of the low voltage input.
