DC in the Greenhouse

The greenhouse market is widely using HID lighting fixtures to illuminate the crops. When using supplemental lighting based on AC, a lot of energy is wasted in the conversion of AC into DC in each lighting fixture. By centralizing conversion of AC to DC, instead of local conversion in each of the lighting fixtures, a lot of energy would be saved.

MVDC/LVDC Converter

Within the IPIN program DC=DECENT, a part of this project involves the research and development of a medium voltage to low voltage DC/DC converter. These converters are multifunctional and can be used in, for example, data centers, storage links possibly combined with a BMS system, solar panel parks, chargers for EV.

The "Stroomversnelling"

In a project renovation of 110,000 homes with a new concept of Zero-energy-meter homes with their own energy generation and energy savings through better insulation and smart systems, Direct Current Ltd implements a centralized DC system in three phases, with the aim to make it possible to have a home working completely on DC.


In the project DC=Decent generated power of local CHPs is being linked to a management system for regulating demand and supply of electric energy. The linking is realized by means of a small-scale network on the basis of direct current (DC), wherein the real-limit is exceeded.

Public Lighting on DC Smart Grid

Direct Current Ltd has developed DC-drivers for LED-lightings and a system for public lightings, as well as an intelligent DC system for a DC smart grid for public lighting. In co-operation with CityTec, this is being implemented in several pilot projects.

Drive Train Electric Mobility

Direct Current Ltd, InnoSys Delft, and university TU Delft, invest, on their own title, in developing a new integrated drive system (drive train), sponsored by the Ministry of EL&I as a part of the HTAS Program by the Government. The development should lead to a greatly improved drive-train in which all parts are aligned.
