Silicon Carbide technology meets these demands with ease, meeting passenger car manufacturers’ need for reliable and efficient e-drive system power electronics.
SEMIKRON has won a multibillion Euro contract starting in 2025 for their new eMPack power module platform for electric vehicle (EV) traction inverters, using “Direct Pressed Die” assembly and connection technology which offers compact, scalable and reliable modules.
eMPowerTM
eMPowerTM platform provides compact, scalable and highly reliable power modules for electric vehicle drive systems. It delivers high power density with industry-benchmark efficiency at cost-effective performance while being highly robust against harsh operating conditions such as cold start-up, acceleration and deceleration.
This platform utilizes a fully sintered Direct Pressed Die (DPD) assembly process with low stray inductance for easy integration of electric vehicle (EV) inverters into industry-leading voltage and current densities, offering wide temperature range and extended aging lifetime to deliver reliability and long-term stability. Automotive grade silicon carbide semiconductors (SiC) semiconductors are also provided as bare die for seamless design integration into design projects.
Passenger car manufacturers require power electronics solutions capable of meeting the rigorous demands of electric drive systems. SEMIKRON’s eMPack power module family, developed to utilize SiC technology, meets these specifications perfectly and forms part of an inverter system that helps reduce greenhouse gas emissions while increasing driving range.
SEMIKRON’s eMPack modules integrate ROHM’s third-generation SiC gate driver ICs for increased efficiency and industry benchmark performance in more compact systems. These modules can be found in applications ranging from electric vehicle traction drives and utility electric vehicles to EV traction drives and utility electric vehicles. An Application Kit featuring both an eMPack module and ROHM gate driver ICs is also available to evaluate performance measurements in the lab, build demo inverters quickly, and optimize control algorithms as necessary.
eMDriveTM
EMDrives are propellantless drives that use microwave radiation to generate force. Though only producing small forces (1.2 +/- 0.1 millinewtons per kilowatt), over long periods they can accelerate spacecraft at incredible speeds while saving weight by eliminating fuel needs like gas.
EMDrive technology is intricate and its proponents have proposed several theories as to its operation. One theory suggests it produces thrust by pushing against quantum vacuum virtual particles in the resonant cavity; another proposes it does so through electromagnetism and Maxwell’s law-derived forces.
Other theories suggest the existence of inertial mass, which asserts that all matter has some amount of kinetic energy, as well as an invisible force proportional to its size. Either way, EMDrive’s claims have been met with considerable scepticism.
Though test results have yet to prove conclusive, Technische Universitat Dresden’s group is keeping at it. Their plan is to continue testing the EMDrive and other devices in an extensive high-tech laboratory equipped with sensors and automated gizmos that will monitor vibrations, thermal fluctuations, resonances and potential sources of thrust – including using a Cavendish balance in order to eliminate electrical and magnetic field effects on measurements.
eMPowerLinkTM
eMPowerLink software application enables the offline transfer of HPLC and UPLC results from Waters Empower Chromatography Data System (CDS). Compatible with on-line and direct injection workflows, as well as being designed to work with both HPLC and UPLC instruments, this system also features financial resources and tools designed to simplify money management – with free 14-day trials offered after signing up, overdraft fees refunded as well as no interest payments on its cash advance product.
Off-line approaches require collecting one channel from an HPLC to allow for sequence advancement (if SII 1.1), as well as pump pressure collection. It is crucial that both CAD run time and Empower sequence run time match in order to synchronize injections.
