DC-DC Unit Diode

In Simple Terms

F1 cars must have a special one-way valve (diode) in their power system that prevents energy from flowing backwards from the DC-DC Unit into the Energy Store. This is a safety feature that must be built into the design and can be checked by inspectors.

• A diode must be installed at the positive high voltage connection of the DC-DC Unit
• The diode acts as a one-way valve, preventing reverse energy flow into the Energy Store (ES)
• This requirement must be guaranteed by the car's design and be visually verifiable during technical inspections
• This is a safety mechanism to protect the electrical power system from damage
