Uninterruptible power-supply systems (UPS)

Uninterruptible power supplies (UPS) are widely deployed to ensure stable operation of power facilities to bolster our information society, in which information and communication systems are not allowed to stop a single moment. The importance of UPS increases year by year as the diversity of user needs highly expands, both of which require system configuration that makes a 24/365 continuous supply reliable, with low running costs (in economic and energy use terms), a compact size that is lightweight, scalable and power-conserving. UNIPARA technology is the standard UPS technology for data centers. Hitachi develops products according to the needs of the marketplace, undertaking system planning, product design and production in a consistent process for every customer to provide the best UPS system for an intended purpose, from small- to large-capacity systems.

High-voltage motor drive inverter for industrial use

We provide high-voltage direct inverters to directly drive high-voltage motors. High-voltage direct inverters are capable of outputting sine wave AC voltage with high conversion efficiency by means of multiple transformers and multi-stage series-connected inverters, contributing to improved equipment controllability and energy conservation.
We are responding to needs for miniaturization and weight reduction by means of logical structure/equipment configuration making free use of diverse simulation technologies such as application of new materials/construction methods, electromagnetic field analysis and heat flow analysis, etc.
We will continue to develop drive systems suited to user needs such as high functionality, high performance and high reliability.

Motor drive inverter for driving dump trucks

Large dump trucks used in mining and other work are gradually converting to electric drive to conserve energy and power. We provide high-voltage high capacity inverters adapted to electric drive systems for electric drive dump trucks with high performance control. In addition to basic driving, we need to overcome technical challenges for implementation of the inverter unit, such as advanced motor drive control that takes control of the vehicle body into account, and capability to adapt to severe environmental conditions such as high-temperature, high altitude and high vibration as we develop products with ever more capacity that can adapt to more advanced control and new applications. The combination of the electric motor/generator and inverter provides the user higher functionality and added value.

High-capacity, ultra-fast multi-port EV charger

Towards the realization of a carbon-neutral society, the transition from internal combustion engine vehicles to electric vehicles (EVs) is progressing worldwide. However, there is an urgent need to expand the charging infrastructure, as charging congestion frequently occurs at service areas and parking areas on highways. As we anticipate an increase in EVs with large-capacity batteries and larger commercial EVs, there is a demand for chargers that can accommodate rapid charging needs. The high-capacity, ultra-fast multi-port EV charger from Hitachi Industrial Products meets those demands and also supports V2X(※), allowing EVs to be utilized as storage batteries, contributing to power stabilization.
Hitachi's high-capacity, ultra-fast multi-port EV charger is a rapid charger equipped with a fast charging connector that complies with Japan-China next-generation charging standard CHAdeMO3.1 (ChaoJi 2). One power unit can now simultaneously connect and charge up to 20 ports (user terminals), supporting ultra-fast charging and V2X, which were not possible with previous products.

※ V2X (Vehicle to Everything) is a communication technology that connects vehicles with various things and enables them to interact with each other.

Power converter equipment for renewable energy power generation

As Japan lacks resources, it has been promoting the installation of renewable energy generation such as photovoltaic power generation systems and wind power generation systems to help mitigate global environmental issues. We provide power conditioner systems (PCS) to distribute to power systems DC power from solar panels and AC power of a frequency suited to the rotation speed of wind turbines. When increasing the amount of power introduced from renewable energy, the generated power of which changes in accord with environmental conditions, there is a great impact on the stability of the power supply. For this reason, technical demands and technology guidelines are discussed and established with the aim of ensuring compatibility, and to deal with these measures in the best way, we are developing and proposing technologies in cooperation with our laboratories, group companies overseas, and R&D institutions outside the company, thereby we are contributing to the stability of power supply and promoting the use of natural energy.

Industrial computers, industrial controllers

Computers and controllers used in social systems that operate all day, every day (such as water treatment systems, transportation systems, and communication systems) and in cutting-edge semiconductor production equipment and medical devices require long-term stable operation and supply. Also, innovations in the globalization of supply chains and production and services utilizing IoT in recent years, require collection of real-time data from both control functions and sensors with edge computing linked with information systems.
We are developing and designing products to meet these needs, such as the “HF-W Series” industrial computer, equipped with RAS (Reliability, Availability, Serviceability) functions that support long-term operation; and the “HF-W/IoT Series” IoT support industrial controller, which integrates a PLC function with this industrial computer to realize seamless connection between operation technology (OT) and information technology (IT) and provide real-time data collection functions, data analysis, and edge processing.
