Emotron AFG - grid feedback
The Emotron AFG is a grid-ready AFE, featuring grid code-compliant software. It allows you to connect directly to a public grid, be part of a microgrid, or form an island grid. With up to 98% efficiency and very low harmonic distortion to supply, it is an excellent choice for any grid application.
The Emotron AFG is ideal for renewable energy applications, OPS, fully electric or hybrid electric applications, both onshore and offshore. The versatile AFG unit can produce 3-phase AC power from DC sources, making it useful for battery use. It can provide bidirectional power for the generator/motor connection to enable e.g. windmill or marine shaft generator control.
The Emotron AFG is delivered in IP54 cabinet builds complete with compact power modules, filters and a controller. The robust, interchangeable and uniquely self-monitored power modules secure your operational efficiency at all times. Let a skilled Emotron project team help you create your own customized solution.

Energy to grid
Emotron AFG grid code drives are often used with renewable energy applications where an energy source such as a windmill, hydropower turbine, thermal power turbine or wave power plant are producing electrical power to a power grid via its electrical generator. Marine shaft generator for PTI/PTO control is another application suitable for the AFG drive.
The AFG can connect to a public grid, be part of a microgrid as well as form an island grid. When connecting to a public grid the AFG has the necessary functions to fulfill the required grid codes.
Energy to batteries, fuel cells and super capacitors
The AFG unit can also be used to produce 3-phase AC power to a grid from DC energy sources such as batteries, fuel cells and super capacitors. Power direction can also be the opposite for e.g. charging batteries or other DC loads. The very flexible AFG unit can momentarily change between the different control modes.
For battery applications, the AFG can be equipped with a special LCL line-filter to remove common mode disturbances without the need for an isolation transformer on the supply side.
The AFG drive is using as active IGBT type rectifier and an AFG-type LCL line-filter together with a control including all necessary grid code functionality as well as voltage/current/power control modes.
Bidirectional power
VFXG is a complete bidirectional drive unit including an AFG supply unit and VSI unit for connection to the AC generator/motor. The AFG supply unit is for connection to DC grids or single DC-sources such as batteries.
