Key components of demanding applications
Hitachi Energy’s semiconductors are key components in a variety of demanding applications in markets like power transmission & distribution, industry, mobility and renewable energy. Customers rely on Hitachi Energy’s high quality power semiconductor products and use them in applications in power ranges from 50 kW to 10 GW.
Applications
- Power transmission and distribution (HVDC, FACTS, STATCOM and others)
- Industry (medium and low-voltage drives, soft starters, UPSs, high-power rectifiers, excitation systems and others)
- Renewable energy (converters for pumped hydro, wind turbines and solar)
- Mobility (rail and subway main and auxiliary drives, trackside power supply / electrical vehicles)
High-power IGBT and diode modules
Hitachi Energy offers three categories of high-power IGBT and diode modules: Insulated, press-pack and the newly launched SiC modules for e-mobility applications.
Insulated modules consist of the new innovative, low inductive phase leg LinPak and the well-established HiPak lineup with more than 15 years and more than 1 million modules in the field. Press-pack modules are a range of pressure contact IGBT modules also known as StakPak. StakPaks are Hitachi Energy’s flagship products with record power ratings up to 5200 V and more than 3000 A.
The new e-mobility module portfolio takes advantage of silicon carbide (SiC) technology, offering benefits like high-current rating in a small package and a with very low stray inductance.
Hitachi Energy’s power IGBT and diode module families are:
- RoadPak modules
- LinPak IGBT & SiC MOSFET modules
- HiPak IGBT and diode modules
- StakPak IGBT press-pack modules
Rapid switching while handling high power levels
IGBTs (Insulated Gate Bipolar Transistors) are widely used in power electronics due to their ability to handle high voltages and currents. They combine the advantages of MOSFETs and bipolar transistors. IGBTs can switch on and off rapidly while handling large power levels. They are commonly used in motor drives, renewable energy systems, and industrial applications.
IGBT’s from Hitachi Energy, ABB branded
Hitachi Energy’s IGBT power modules are available from 1700 to 6500 volt as single, dual / phase-leg, chopper IGBT and dual diode modules. The high-power HiPak IGBT modules feature low losses combined with soft-switching performance and record-breaking Safe Operating Area (SOA). The newly introduced 62Pak and LoPak fast switching medium-power IGBT modules feature lowest switching losses, full 175 °C operation with full square SOA and standard package allowing drop-in replacement.
Press pack IGBT-modules for applications requiring series connection
StakPak is a family of high power insulated gate bipolar transistor (IGBT) press-packs and diodes in an advanced modular housing that guarantees uniform chip pressure in multiple-device stacks.
Although the most common package for IGBTs is the isolated module, for applications requiring series connection, press-packs are preferred because of the ease with which they can be connected electrically and mechanically in series and because of their inherent ability to conduct in the shorted state – an essential feature where redundancy is required. Since IGBTs feature multiple parallel chips, there is a challenge – with conventional press-packs – in assuring uniform pressure on all chips. This problem was solved with a new patented spring technology.
The StakPak, optimized for series connection, features a modular concept based on submodules fitted in a fiberglass reinforced frame, which allows a flexible realisation of a range of products for different current ratings and IGBT/diode ratios.
