ACS880-1607 DC-DC converters

DC/DC converter transfers energy from a common DC bus of a multidrive into an external energy storage. From there it can transfer the energy back to the DC bus when needed.

For energy storage and reuse

Applications for energy storage and reuse are found in a range of industries, such as marine (heave and peak load compensation) and process industry (electrical braking or DC bus voltage stabilization). The converter unit consists of R8i and converter units.

Customer benefits include reduced costs (less fuel consumption, less or smaller generators in ships), improved ship performance and safety in critical situations.

Key benefits

The all-compatible multidrives comes with various types of supply units including diode supply units and regenerative supply units and they are available as air and liquid cooled versions. Single supply and DC bus arrangement with several inverters reduce line power and system size. Utilize premium control of virtually any type of AC motor with direct torque control (DTC), including induction and permanent magnet motors and synchronous machines.

Process stability and energy savings

Ensures stable process control while optimizing energy efficiency across various applications.

Energy efficiency in hybrid systems

Batteries and supercapacitors can be used for peak load compensation reducing the needed generator capacity and allowing smaller generators to be used.

Optimal process control

Heave and peak load compensation with batteries or supercapacitors enables dynamic load response.

Emergency power

Batteries can provide emergency power for mission critical applications, like propulsion in ships.

Modular Design

Customizable and scalable architecture to meet various power requirements.

Flexible Installation

Suitable for multiple industries and can be integrated into various systems.
