What is the difference between an inverter and DC/DC converter in an electric vehicle?

Much like how internal combustion engines and alternators work together on conventional vehicles, hybrid cars and electric motors use inverters and converters to manage power to and from the battery pack to the motors and other on-board systems.

Inverters transform direct current (DC) from the battery into alternating current (AC) to power the vehicle. Inverters also control the motor and convert it to a generator, transferring braking energy back into the battery.

Converters control the DC voltage from the battery, either stepping it up or down based on the system and the power needed. DC/DC converters usually step down the high voltage from the battery pack to the 12-volts used by radios, headlights, and more.

An OE solution for aftermarket power electronics

Inverters and converters work together to manage the vehicle's electric drive and accessory systems. However, many of today’s inverters and converters can be complex, expensive, and prone to failure from excessive heat. They are also heavy and take up a lot of room on the vehicle, compromising both trunk and passenger compartment space. Delphi OE solution combines the inverter and DC/DC converter into one unit.

Delphi CIDD is cost-effective and saves vital weight and space in hybrids (HEV), plug-in hybrid electric (PHEV), and electric vehicles (EV). And by leveraging patented OE technology - Viper-enabled inverter’s double-sided cooling - it tackles the issue of overheating, allowing higher power outputs from a smaller package and increased range.

Combined Inverter and DC/DC Converter (CIDD)

Enhances durability and reliability through features designed to withstand under the hood and environmental factors such as debris and temperature extremes.
Improves voltage distribution functionality, enabling both low-side and high-side power for everything from headlights to power steering and air conditioning systems.
Provides maximum packaging flexibility and space savings by moving the DC/DC unit from its standard location in the rear to the front of the vehicle.
Enables better power range and minimizing power losses through the elimination of cabling, cooling hoses, connections, and housings, all while simplifying maintenance and repair.

Resource Highlights

A DPF sensor is crucial for exhaust systems and emissions levels. Learn how to replace one to industry standards.

How do I remove the DPF sensor?

Firstly, you’ll need to remove the engine cover. Next, remove the electrical connector from the sensor by putting pressure on the connector and press it in. Now lift the tab and you should be able remove it with a pull. Lastly, you’ll need to remove the pipework from the sensor before you take it out.

How do I remove the pipework?

Unscrew the retaining screw from the sensor. Once you’ve done this you can start work on unfixing the pipework. Using a pair of pliers, loosen the clips from the pipework. Now, slide the pipework off the sensor.

How do I visually inspect the new part?

Simply put the old and new parts next to each other and check that the barbs are the same diameter and the electrical keyways are the same.

How do I fit the new part?

Essentially, do what you’ve just done in reverse. When it comes to fitting the clips to the pipework, use the pliers again making sure the clips are snug and not too close to the edge. Relocate the sensor into the clip, place it against the backing plate and put the retaining screw back in. Now, reattach the electrical connector, pushing down firmly until you hear a click that lets you know it’s secure. Replace the engine cover and use a diagnostic tool to erase any fault codes and check live data.
