Schematics
Voltage Sense
- We will have isolated voltage feedback. The voltage will be transmitted via a SPI ADC over a digital isolator.
Charger
- LT3750 Design from previous, with modifications to support ~9.5A peak charge current
- Key parts
- FET FQB34N20 FQB34N20TM_AM002CT-ND (overkill - but needed after the fire on rev 1 - 2007)
- LT3750 LT3750EMS#PBF-ND
- Cap below
Trigger
Parts
Digital Isolator
Isolated DC-DC Power Supply
Capacitor
We are gonna shoot for between 4000-5000uF by using two of the following
2700uF caps
- Vendor - Digikey
- Vendor Part Number - P13180-ND
- Manufacturer - Panasonic
- Manufacturer Part Number - ECE-T2EP272EA
- Cost - $12.86 quant 10
- Description - 2700uF kicker capacitors
- datasheet
- digikey
Capacitor Charger
Based on the Linear LT3750 controller as in years past
IGBT
- Vendor - Digikey
- Vendor Part Number - FGA180N33ATTU-ND
- Manufacturer - Fairchild
- Manufacturer Part Number - FGA180N33ATTU
- Cost - $3.39
- digikey
- Fairchild FGA180N33ATDTU link
Solenoid
See the Solenoid Development page for more information. For logistics reasons, we may purchase a solenoid as we did last year and take it apart for use in our mounting apparatus.
