In 2018 we continued our R&D investments with specific focus on our fast growing businesses for electro-mobility, networking, datacenters and industrial power. Major extensions of the product lines where achieved as well as continued improvement of our product’s key features efficiency, power density and digital intelligence. Additionally, Delta R&D has increased the application range and customer base respectively of its power technology products like industrial wireless charging, combined charge units for the electro-mobility and artificial intelligence.

The healthy view of the markets, their customers and their demands combined together with the R&D manpower’s know-how and strengths is the door to Delta’s competitiveness and leadership in green environment and efficient energy saving power devices.

Delta has a worldwide network of R&D centers located in Asia and Europe. These centers cooperating very close together. Delta R&D engaged globally in the cooperation with the renowned universities. We participate in several research programs to ensure sustainable growth with unique technology. This collaboration is a big benefit with innovative and green ideas combined together with the Delta R&D expertise. This is a trustable way to establish a long-term and continuous relationship with young and experienced people, to take care of high-tech, new and sustainable products.

Delta beliefs in its close cooperation with key customers. Our customers are both worldwide market leaders as well as innovators for new technology products. Delta welcomes the new customers in new industries, which give the opportunity to drive new processes and implement new technologies for the upcoming market challenges.

Through Delta’s green philosophy, we continued our leadership in the electronic world, which has been pursued over decades. Delta strengthens and follows its wish to reduce world pollution.

Research and Development (R&D) and Server Storage Networking (SNT)

“Moore´s law has ended” CPUs can´t achieve 1.5x performance increase every year any more. With GPU chips a factor 1000 performance improvement within 10 years.

3000W 6000W

Server Storage Networking (SNT)

Delta’s worldwide R&D team has accumulated decades of experience and knowledge in developing highly sophisticated customized power supplies for well-known companies in the IT domain, networking and telecommunications industry. We have applied our knowledge to develop new products, which rank far beyond traditional standard power supplies. This knowledge enables us to become a system solution provider.

In 2018 R&D team succeeded to win a new important customer in a new technology market : this customer is the market leader in GPU application which are mainly used for artificial intelligence applications including machine learning (ML) and deep learning (DL) as well as for autonomous driving in future. Here Delta received an important award for DGX2/HGX2 platform.

This new GPU computing technology allows exponential growth of computing power again which up to date had come to an saturation point with traditional CPU chips (Intel & AMD) (see graph, blue curve).

Delta R&D has developed special power supply technology to feed these GPU-processors. The DGX2 server drawer is using six of our Standard 1U PSUs with 3000W output power with an output voltage of 54V. The main challenge of these power supplies is to provide extreme peak load demand of these new processors of > 200% with up to 5A/us.

In parallel to this new technology we have developed new products with up to 98% peak efficiency delivering 3000W and 6000W output power achieving power densities of larger 60 W/in³ for high performance computing in datacenters and networking. Here, Delta R&D is designing a 6000W/54V power supply using latest circuit technology with GaN devices to achieve both high density and high efficiency at the same time.

In addition to sole power supply design, Delta R&D’s core achievement was the continuous extension of our product offering to additional products used in Datacenters, like complete sever shelfs with distribution panel and power distribution units.

Solutions for Electric Vehicles (EV)

In 2018, Delta R&D continued to develop and refine an advanced technology platform for On-Board-Chargers, which allows meeting the increasingly challenging customer requirements while at the same time generating a high re-use of the platforms across different projects. These platforms enabled us to receive new projects from multiple new customers. These includes units, which combine our On-Board-Charger family of 22kW, 15kW and 7.2kW with 12V-DCDC converters in one package to allow a high degree of integration of both – functionality and power density. Additionally, we received the project award of a new, high efficient 7.2kW 1-phase On-Board-Charger.

By deriving it from these platforms, Delta achieved a very high maturity level of this unit very fast resulting in short development times.

Additionally, Delta continued to extend its low voltage DCDC converter portfolio. Here, we received the project award for 2.5kW unit, which we prototyped in 2018 in the framework of an advanced project and finalized the product in 2018.

Delta drives to strengthen its existing customer base as well as to enter into new customers by leveraging and extending the existing technology and adapting it to the specific customer needs. Delta investigates new solutions of incorporating various core application (e.g., On-Board-Charger, DCDC Converter, DC Charging Control, Heating System) into one package to meet customer demand.

Custom Designed Power Supplies for Industrial/ Medical (IM) Device Applications and Charger for Industrial Electrical Vehicle (IEV)

Several major innovations have been realized by Delta’s R&D team in 2018 to provide our customers with an outstanding cost-performance ratio for industrial and medical applications, such as factory automation, machinery and robotics, battery charging technology, ultrasound application, artificial respiration and dialysis.

The usage of advanced power and control technology has led to products with best parameters as stability, efficiency, operation flexibility, robustness and reliability.

Delta R&D team designed a 20kW and a 30kW wireless module for fork-lift charging. Customer feedback is extreme positive to this outstanding product. Other customers have followed to introduce this new technology in their applications.

22kW Combined Charge Unit



The Opportunity Charging for Li-Ion Efficiency delivers a very high flexibility for the customers. Some Key Requirements:

  • • CEC California Energy Commission > 90 % under full load, less than 20 W losses in Stand by
  • • Charging Current 600A
  • • Operational Airgap (y) 100-150mm
  • • Displacement ( x , z ) +/-75 mm , +/- 50 mm
  • • Transformer Secondary Charging Pad 55 * 700 * 520 mm
  • • Transformer Primary Charging Pad 50 * 800 * 600 mm

Throughout 2017 and 2018 the R&D team worked on several Industrial battery charger platforms. Gaining a large US customer with this technology enabled in the same time to tackle the mass production market with these new modular power units and cabinets.

The primary application is the forklift truck fast charging industry. This type of battery charger operates at a very high charge rate and allows trucks to be re-charged fast during short breaks. This results in 24/7 operation of the trucks during the work week, minimizing battery changeovers and improving user productivity

In 2018 we produced mass production for 48V batteries and several more design variants are following in early 2019. Novel software features installed on the charger module allow the user to integrate easily the Delta hardware into their charger systems. Current sharing between modules is handled easily without any setup or intervention from the user, allowing systems to be quickly and easily configured. Problems such as damaged or premature DC connector wear are avoided using a smart software disconnection feature that saves sparking if the user accidently disconnects during a fast recharge.
