Powertrain Electrification Power ElectronicsHigh Voltage Power Box
The High Voltage Power Box combines the functionality of an Onboard Charger (OBC), a DC/DC converter and a PDU (Power Distribution Unit). The OBC is the interface between the car and the public grid. It converts the energy from the network grid AC (Alternative Current) source to DC (Direct Current) voltage of the car high voltage battery in respect with the public grid and the regulations.

Powertrain Electrification Power ElectronicsCharger converter: High Voltage Onboard Charger and DC/DC Converter Combo
The high voltage combo OBC DC/DC combines the functionality of an Onboard Charger (OBC) with that of a DC/DC converter (DC/DC). The OBC is the interface between the car and the public grid, it converts the energy from the grid network AC (Alternative Current) source to the DC (Direct Current) voltage of the car high voltage battery in respect with the public grid and regulations.

Powertrain Electrification Power ElectronicsHigh Voltage DC/DC Converter
The High Voltage DC/DC converter is a reversible electronic device which lowers the Direct Current from the High Voltage battery to a Low Voltage Direct Current used by most of the vehicle electrical equipment (e.g. dashboard, electric window…). The DC/DC converter is also in charge of keeping the passengers safe by insulating them from the High Voltage electricity network.

Powertrain Electrification Power ElectronicsEV High Voltage On-Board Charger
The electric vehicle onboard charger converts alternative current available on the grid into direct current that can charge the vehicle’s battery. Almost all the energy charged in the vehicle is flowing through the onboard charger’s power electronics.

Powertrain Electrification Power Electronics48V Inverter
The 48V inverter, the electronic component that drives the 48V eMotor (electric motor), is able to be integrated on all architectures beyond P0 (alternator position) meaning between the engine and the gearbox or in the gearbox or on the vehicle rear axle.
Valeo produces its own electronics including the power modules based on Transfer Molded Leadframe (TML) which allow Valeo to have a multisourcing strategy on the Metal–Oxide–Semiconductor Field-Effect Transistor (MOSFET).

Powertrain Electrification Power Electronics48V to 12V DCDC Converter
The 48V to 12V converter is a car electronic device which converts Direct Current to Direct Current, adapting the voltage of the 48V electrical network to the 12V electrical network.
In our case, the 48V to 12V DC-DC converter is bi-directional as it provides Direct Current from 48V network to 12V network (buck function) but also from 12V network to 48V network (boost function).

Powertrain Electrification Power ElectronicsHigh Voltage Inverter 400V Si
The 400V inverter is the brain at the heart of the electric powertrain, it controls the electric motor. It converts Direct Current (DC) from the battery to Alternative Current (AC) to power the electric motor. It can also be used in reverse mode to charge the battery by transforming kinetic energy from the vehicle into electrical energy that can be stored in the battery. Valeo inverters are based on a scalable platform able to suit Si or SiC, for 400V & 800V. It is based on a highly standardized hardware and software architecture.
