# Microgram: voltage-topology-tradeoff

`station__algovigilance__microgram-voltage-topology-tradeoff` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Evaluates 200V vs 400V bus topology for wearable power systems. Routes by voltage level and computes wire gauge, insulation weight, current magnitude, and motor efficiency tradeoffs. Higher voltage = thinner wire + better motor efficiency but harder insulation in a body-worn system.

## Agent metadata

- `idempotent`: true
- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
- `cost_tokens_estimate`: unknown

## Input schema

- `bus_voltage_v` *number* (required) — Nominal bus voltage in volts
- `max_power_kw` *number* (required) — Maximum continuous power demand in kilowatts
- `total_wire_length_m` *number* — Total wiring run length in meters (default ~10m for exosuit)
- `environment` *string* — Operating environment — affects insulation requirements
