MEP EP#249: How Soft Are Your Diodes?

Parker

  • Signed up for the EXTRA LIFE charity this year to raise money for the Texas Children's Hospital
    • This Saturday (Nov 7th) Parker will be broadcasting a 24 hour video game stream
    • Will be playing the Half-Life 2 video game all the way through
      • This includes the two episode expansions to the base campaign
      • Difficulty level will be set to 'Hard' and I will be attempting to unlock all the achievements at the same time.
      • Donations are tax-deductible and 100% of it goes to the hospital
      • Learning some javascript to build plugins for the stream
      • PinoTaur REV3 has gone gold
        • Added more current sensing
          • Low Current Allegro ACS70331EESATR-005B3
          • High Current Allegro ACS711KEXLT-15AB-T
          • Changed Relay to a socketed relay type
            • ISO micro relays type
            • On PCB flyback diodes for coils
              • MRA4004
              • Relay is driven by both the MCU and the Fault pin on the high current sensing IC
              • Walmart fires store robots
                • Saw improvements in inventory control with the robots, but not enough of an improvement in revenues and other measures.
                • One premise is that stores will sell more goods if the shelves are stocked and wanted items are made available

                  • How soft are your diodes?
                    • Softness factor - a definition of the reverse current characteristic
                    • Ta = time when charge from depletion region is removed
                    • Tb = time when charge from semiconductor region is removed
                    • S-factor = tb/ta
                      • S-factor = unity = soft recovery
                      • S-factor unity = fast or snappy-recovery
                      • General purpose/fast recovery (FRED diodes)
                      • The SSPS?
                        • @zane is going back and listening to episode 1
                        • What was the SSPS?
                          • What were the specifications????
                          • Where did we leave off
                            • ...more
