Hello Twitter We are students from @HS_Reutlingen and E&D @[email protected] designing an ASIC on the base of our predecessors Electronics & Drives - iSCREAM. We are excited to share our project! Expect interesting content in the upcoming time 👀🧠🛠️. #PowerElectronics #Microelectronics

An extension of our Electronics & Drives - RIDE to the Electronics & Drives - iSCREAM ASIC is the automatic start of the SRM. Therefore we have developed the StartUp process, which determines the position sensorless by feeding voltage pulses into the SRM. E&D @[email protected] #PowerElectronics #Microelectronics

Part of the Electronics & Drives - RIDE ASIC is the digitally adjustable hysteresis of the motor control. The hysteresis is implemented by using the current bank and the comparator. It can be set using a DAC (A) and a 4-Bit word (B). E&D @[email protected] #PowerElectronics #Microelectronics

Our SPI-based digital interface is tested on an FPGA.  Via multiple SPI packets, the string "Digitale Schnittstelle" is written into eight registers which are linked to a display as visual feedback.  E&D @[email protected] #Microelectronics #Powerelectronics

You can see the current mirror schematic and layout of the HCC . The resistors and NMOS are built up from multiple identical basic elements in common-centroid arrangement. With this approach the influence of production tolerances is reduced. #Microelectronics #Powerelectronics

During StartUp we measure all phase currents of the SRM after a digitally adjustable time. These have a different di/dt due to different inductance values of the phases at the start position of the SRM. E&D @[email protected] #Powerelectronics #Microelectronics

66. MPC-Workshop an der @THU_Ulm: Best Paper Award für unser #Master-Projektteam Electronics & Drives - RIDE für seinen Beitrag zur Entwicklungen eines digital konfigurierbaren ASICs zur Ansteuerung geschalteter Reluktanzmotoren. Herzlichen Glückwunsch! #Mikroelektronik @HS_Reutlingen

We are back! We finished the first semester with a successful mixed-signal ASIC design. During the meantime, we developed the power electronics necessary to power switched reluctance motors up to 320 Volts! Stay tuned. E&D @[email protected] #Powerelectronics #Microelectronics
