Delphi DC-DC Converter
Delphi Universal 2.2kW DC/DC Converter creates DC voltages in hybrid and electric vehicles necessary to power accessories and the HVAC system. Liquid-cooled, the DC-DC converter operates at input voltages from 216 to 422VDC with a power range to 2.2kW.
Benefits
- In production
- Proven automotive design, reliable even in the harsh environment of the engine compartment
- Highly efficient conversion using synchronous rectification
- Applicable to multiple vehicle platforms without re-engineering
Features
- Analog output voltage is adjustable through CAN serial communication; 11V – 15.5V
- Bi-directional capability supports charging of high-voltage battery
- Over-voltage, over-current, and over-temperature protection with fault reporting
- CAN serial interface
Mounting Information (Vibration Dampening)
There are no "dampening feet" used with our DC/DC Converter. It all cases where we have supplied it to a vehicle manufacturer, it has been mounted underhood, out of the splash zone, and typically on a frame or bracket.
This bracket utilizes the mounting bosses per the description in the U2C Customer Manual (i.e., bolt size and thread type, grounding cable location, etc.). It many cases the bracket itself is attached to the engine, but the U2C is never directly attached to the engine.
The U2C has been validated to operate at underhood temperatures and with a vibration profile commensurate with being on a frame attached to the powerplant. Using it in that manner should preclude the need for any type of additional "dampening".

HV Connector Change
As shown in the above figure, the circular HV connector has been changed to a square connector recently. The following are notes about the changes:
- Delphi's current HV connecter from Amphenol was selected by previous customers due to its use in other areas of their vehicle.
- Delphi-Packard (PED) has an existing HV header and mating connection system that has been applied by modifying the plastic body of the header. (ONLY)
- A small modification is required to the converter housing to accommodate the PED header connecter.
- The mating connecters are currently available from Packard
- Part Number for the Converter assembly with PED is: 28304007-01
General Specs
- Rated current - 12.7 A/15 A
- Voltage Level - 450 V (DC)
- Temperature Range - -40 deg C to +110 deg C
