Combined Inverter and DC/DC Converter

Delphi Combined Inverter and DC/DC Converter (CIDD) is our OE solution for hybrids (HEV), plug-in hybrid electric (PHEV), and battery electric vehicles (BEV) that delivers maximum power density in a lighter, smaller, cost-effective package.

As the market for electric cars rapidly increases, independent aftermarket garages will need the right replacement part for the repair. That’s why Delphi is offering exact OE performance with our power electronic aftermarket parts.

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.

Here we’re taking a look at how practical it is to run an EV using your solar panels.

As Matt, our Delphi expert explains in this video, running an EV from solar is possible (depending on the size and power of your solar array), although it’s much easier during the summer. Watch this video to learn:

Some basic calculations to show you how much energy you need to charge your vehicle effectively
The reason why solar is not 100% efficient as an energy source
Matt’s personal experience of running an EV from solar

Is solar better for the environment when I’m charging my EV?

Yes, is the short answer. That’s because you’re guaranteeing that the energy you’re using is coming from a renewable source – which is something you can’t always be sure of if you’re drawing electricity from the grid.

Is extra equipment needed for solar charging?

Yes. You can only charge an EV with solar panels if you've got the right setup. That means investing in a solar PV (photovoltaic) system if you don’t already have one, a solar compatible EV charger and, as an option, a solar battery which will mean you can charge your vehicle at night.

How long does it take to charge an EV with a standard solar setup?

A typical domestic solar PV system can generate between 1 and 4 kilowatts of power (kWp). This is enough to fully charge an EV with a battery capacity of 40 kWh in slightly more than eight hours.
