DC/DC converter

High performance DC/DC converter

The high performance DC / DC converter range of 4fores, known as “kW series”, has been conceived to satisfy the needs of energy conversion in DC obtaining the maximum technically possible efficiency (up to 97.7% efficiency) in a minimum size, allowing to reach very high power densities (up to 0.58 kW / liter).

The converters in our kW series have rated power between 3.5 and 6 kW per module, being available of operating at voltage range between 20 and 800 V at the input and output. The products are available in buck and boost configuration, with either unidirectional or bidirectional power flow.

The converters in our kW range are a scalable solution. Connecting modules in parallel it is possible to increase the power of the system, which makes it a redundant and very flexible solution and potentially adaptable to any application: PV / renewable, storage, fuel cells, capacitor banks, electric vehicle, machinery and test ...
