# Industrial Specification: Thruster Interface Units

## 1. Technical Definition
Electronic control modules that manage communication and command execution between dynamic positioning systems and vessel thrusters.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24-32 VDC input voltage, -25°C to +70°C ambient temperature, 0-100% PWM duty cycle**. Failure boundary: **Input voltage exceeding 36 VDC causes MOSFET gate oxide breakdown, ambient temperature exceeding 85°C triggers thermal shutdown, PWM frequency deviation beyond ±5% of 1 kHz nominal causes resonance**, Mechanism: **Electromigration in copper traces at current densities exceeding 10^6 A/cm², dielectric breakdown in 100 nm gate oxide at electric fields &gt;10 MV/cm, solder joint fatigue due to CTE mismatch between FR-4 PCB (17 ppm/°C) and ceramic capacitors (7 ppm/°C)**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
