Cost-effective Optimal sMall PAssive ComponenT based high efficiency Adjustable Speed Drives for Low Dynamic Performance Applications

The CompactASD project addresses the societal challenge of reducing energy consumption and greenhouse gas emissions by developing a cost-effective, energy-efficient Adjustable Speed Drive (ASD) for low dynamic performance applications. The project aims to reduce power losses by up to 20% and achieve a 10% price reduction compared to existing ASDs, contributing to global efforts to mitigate climate change.


The scope of the project involves leveraging modern power electronics, reducing the size of passive components, and implementing advanced control algorithms to optimize cost, energy efficiency, performance, and footprint. The technology will be demonstrated in transport refrigeration units for refrigerated containers, with potential applications in HVAC, refrigeration, and industrial manufacturing.


The expected outcomes include significant energy savings, cost reductions, and positive environmental impact, while strengthening the market position of the participating companies. The project is anticipated to contribute to energy policy goals by improving energy efficiency and reducing reliance on fossil fuels, leading to reduced CO2 emissions.

Innovatively, the CompactASD project employs a hybrid approach combining silicon and wide-bandgap semiconductor devices for cost-effective power conversion. The use of smaller passive components contributes to reduced size, weight, and cost, while advanced power topologies and circuit layouts optimize performance. This innovative approach is expected to increase market share for the project partners in the growing ASD market.
