Questions
R we able to flash our own algorithms
What kind of telemetry data
temperature
current, voltage
operating model
limits
curve tracing (IV curve)
How did you follow the design process?
Issues/challenges with the MPPT as he designed
Don't rush building these MPPT
Testing
Controls
Doing it digitally makes it prone to bugs
Redline → Shut off all switches
Current limits (control loop)
cascaded control loop
current set point in the control loop
done in software
Voltage limits
Keep in mind to be careful while routine to decrease capacitance → decreases
Filter to measure frequency(?)
Transient frequency is at that frequency
control loop run faster than the resonant frequency of the LC
digital control loop should be fast

Notes
Efficiency
modeling the losses of the components
GaN Fets
optimization algorithms
Open-source hardware
There’s a tool that can help us view telemetry data and our own firmware
microprocessor used: STM G4 series, high-resolution timer
Switching frequency
constant
40 kHz
