Digital isolation in hybrid and electric vehicles
Isolation requirements in transportation
Hybrid and electric drivetrains in cars, trucks and two-wheelers are introducing new, previously unknown challenges in the transportation industry. The 12V board net is now complemented with a 400V or higher battery and power system, which introduces a completely new set of requirements for the car OEMs and system module providers. An isolation need is present in all function of the HEV/EV like the high voltage battery, the DC/DC converter, the inverter for driving the electric motor, but also for the charger module connected to the 230V / 380V power grid - see figure 1.
