#### **The Unseen Power Crisis on Rails**

While passengers experience seamless acceleration, railway engineers battle a hidden challenge: **every 1% loss in traction efficiency costs operators over $200,000 annually per train fleet**. Traditional power modules simply can't keep up.

> *"Switching to advanced IGBT brick modules dropped our energy consumption by 18% and increased MTBF to over 5 million hours."*

> – Dr. Chen, Lead Propulsion Engineer, CRRC Qingdao Sifang

**Performance Benchmark**:

| **Parameter**       | Standard IGBT     | SiC-Hybrid IGBT Brick |

|---------------------|-------------------|-----------------------|

| Switching Frequency | 2-5 kHz           | **16-20 kHz**         |

| Efficiency @ 150°C  | 92.5%             | **98.7%**             |

| Heat Loss           | 1200W/module      | **400W/module**       |

| Operating Junction  | 150°C             | **175°C**             |

##### **2. Brick Power Modules: The System-Level Game Changer**

**Why Packaging Matters**:

- **Direct Liquid Cooling**: 3x heat dissipation vs. air cooling

- **Low-Inductance Design**: <10nH for reduced voltage spike

- **Press-Fit Contacts**: Vibration-resistant for 20G operational shock

- **Customizable Topology**: Half-bridge, chopper, 3-phase options

**Real-World Impact**:

- **35% volume reduction** in traction converter cabinets

- **92% fewer solder joints** vs. discrete designs

- **Maintenance-free operation** for 1.6 million km
