# Industrial Specification: Gate Driver Board

## 1. Technical Definition
A specialized printed circuit board that controls the switching of power semiconductor devices (typically IGBTs or MOSFETs) in an inverter module.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-20 VDC input voltage, -40°C to +125°C ambient temperature, 0-100 kHz switching frequency**. Failure boundary: **Input voltage exceeding 25 VDC causes gate oxide breakdown, junction temperature exceeding 150°C triggers thermal runaway, dv/dt exceeding 50 V/ns induces parasitic turn-on**, Mechanism: **Electromigration in copper traces at current densities above 10^6 A/cm², dielectric breakdown at electric fields exceeding 10 MV/m in gate oxide, bond wire lift-off at thermal cycling exceeding 1000 cycles ΔT=100°C**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$
