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)
Diodes for various applications
Diodes are used in a number of different applications. Each of these applications sets different requirements on the diodes’ characteristics. Inverter applications ask for fast recovery diodes with soft-switching characteristics, high-current rectifiers demand diodes with low on-state losses, medium-power rectifiers benefit from diodes with avalanche capability and welding rectifiers require highest current in the smallest package.
Hitachi Energy offers four press-pack diode families that meet these requirements:
- Fast recovery diodes
- Standard rectifier diodes
- Avalanche diodes
- Welding diodes
