I. Microchip IGBT Modules: The Core Choice for Medium- and High-Voltage High-Power Applications

Insulated Gate Bipolar Transistor (IGBT) modules are one of the core products in Microchip’s power module family. They combine the high input impedance and fast switching characteristics of MOSFETs with the high voltage and high current handling capabilities of Bipolar Junction Transistors (BJTs). Designed specifically for medium- and high-voltage, high-power conversion applications, they are key components in industrial automation, renewable energy generation, and rail transport sectors, and are often referred to as the “power CPU of power electronics”.

Core Technologies and Product Features

Microchip’s IGBT modules have undergone iterative upgrades through multiple generations of trench technology, from the early Trench 3 series to the latest Trench 7 series, with continuous performance optimisation. The core features are as follows:

- High reliability: The modules integrate IGBT chips and freewheeling diodes internally, utilising high-efficiency insulating materials in the packaging. They offer excellent thermal stability and surge resistance, with a maximum operating junction temperature of 175°C and strong short-circuit withstand capability, making them suitable for harsh industrial environments.

- Flexible Adaptability: The range covers various topologies, including single-transistor, half-bridge and full-bridge configurations. Voltage ratings span the medium-to-high voltage range, with rated currents ranging from tens to hundreds of amperes. The DualPack 3 (DP3) series, in particular, offers a rated current range of 300–900 A and voltage ratings of 1200 V and 1700 V, catering to diverse power requirements.

- Easy integration: Utilising industry-standard packages (such as EconoDUAL™-compatible and PQ packages), the DP3 series features a compact footprint (approximately 152 mm × 62 mm × 20 mm), enabling increased output power without the need to parallel multiple modules, thereby simplifying system design and reducing Bill of Materials (BOM) costs.
