Introduction to Schaeffler's Innovative Inverter Brick
Leading the charge in electric mobility, Schaeffler has embraced ROHM Semiconductor’s cutting-edge silicon carbide (SiC) MOSFET bare chips in their newly developed high-voltage inverter brick, which has recently advanced into mass production. This collaboration between the two companies exemplifies a strategic partnership aimed at revolutionizing the automotive industry.
Power and Performance of the Inverter Brick
The cutting-edge inverter brick represents a crucial building block for electric drive systems, converting logic signals into high-frequency current pulses to energize the vehicle's electric motor. Schaeffler's new design allows an impressive output by pushing the maximum battery voltage significantly beyond the standard 800 volts and managing RMS currents of up to 650 amps. This innovation not only increases the electric vehicle's performance but also reduces overall size, creating what can only be described as a compact powerhouse.
Design Focus: Modularity and Scalability
The evolution of electric mobility solutions relies heavily on effective design principles like modularity and scalability. Schaeffler has leveraged these concepts by introducing a readily integrated inverter brick that embodies these attributes. The development cycle for this advanced product took just one year, illustrating Schaeffler’s commitment to innovation and rapid go-to-market strategies.
Comprehensive Features of the Inverter Brick
Essential components within the inverter brick include a power module for pulse-width modulation (PWM) of current pulses, a DC link capacitor, a DC link, and an advanced cooling system. Notably, the integrated DC boost function allows vehicles designed with 800V architectures to recharge at 400V stations while maintaining their charging speed, creating a seamless user experience.
