Power electronics are at the heart of modern electric vehicles. Components for power electronics are supplied by MAHLE. During AC charging, the power flows through a MAHLE noise filter and a MAHLE onboard charger toward the battery. A MAHLE DC/DC converter supplies the 12-volt unit with power, and a MAHLE inverter ensures precise control of the traction motor and processes the energy obtained during the recuperation process.
“Part of our dual strategy is the continuous expansion of our already broad product portfolio in the area of power electronics. Robustness and a high power density are central to our development activities,” says Dr Jörg Stratmann, Chairman of the Management Board and CEO of MAHLE.
Noise filters are crucial for compliance with the strict rules on minimising electrical interference. With minimal power loss, MAHLE noise filters cover a frequency band of 150 kilohertz to 300megahertz with a voltage of 400 volts and are extremely robust and compact. They also identify the type of charging current and verify the quality of the ground connection.
MAHLE’s onboard chargers have a particularly high power density and are protected against under- and overvoltage, overcurrent, and overheating from both a software and a hardware perspective. The DC/DC converters from MAHLE separate the high- and low-voltage electrical systems safely and reliably. They are flexible in terms of installation space and design, and are also protected against under- and overvoltage, overcurrent, and overheating, said the company.
MAHLE inverters are modular and scalable, cover a voltage range from 400 to 800 volts, and are compatible with all common types of the traction motor.
