HV Pulse Power Design

Worked for 1 min 26 sec

The architecture checks out: the HV and low-voltage grounds remain isolated, and the hardware fault line independently disables both charger and inverter enables. Remaining electrical-check items are external module feedback/telemetry stubs plus three pre-existing control-power warnings; I’m documenting these limits and generating firmware, bring-up, and safety files now.

One real inherited issue remains: comparator U2:2IN− is floating. I’m sending a focused correction to tie that unused comparator channel into a defined safe state and to clarify the original 5 V control-source connection, then I’ll re-run only those checks.

Received notification from "Hybrid Power Prototype" that it finished — picking the work back up.

Expanded the schematic from 92 to 172 components with:

Six-cell graphene/EDLC supercapacitor interface
External 4S LiFePO₄/BMS interface
Isolated charger and bidirectional converter interfaces
Channel 4 auxiliary self-power path with startup-power ORing
ESP32-WROOM-32E and three ADS1115 telemetry ADCs
Independent hardware charger/inverter shutdown
Protected 40 A-class external inverter interface
Separate HV GND and low-voltage LV_GND

Floating comparator and control-power errors were corrected; floating-pin and missing-power checks are now clean.

Open items

Exact isolated charger, bidirectional converter, BMS, and active supercapacitor-balancer modules require measured capture voltage, source impedance, and sustainable power.
The new components still need PCB placement; routing has not started.
The inverter remains an external certified module rather than onboard mains circuitry.

Next steps

Re-size and place all 172 footprints by power domain.
Select the external converter and BMS modules from measured source data.
Apply HV/high-current layout rules and isolation boundaries.
Review placement before routing.
