Emotron VSI - generator control
Gain control over your motor/generator with Emotron VSI. Generate variable 3-phase AC voltage and frequency to precisely manage your AC motor/generator - whether it is asynchronous, PMSM, or SynRM. One or more VSI units can be connected and fed from any DC-voltage source, e.g. the DC-bus output of an AFR or AFG DC-supply unit or a DC-grid. Let a skilled Emotron project team help you create your own customized solution.

Details
Bidirectional power handling for motoring and generating
Since the VSI unit enables bidirectional power handling for both motoring and generating and is ideal for applications within renewable energy, shore-to-ship power or marine applications.
A flexible modular component for your cabinet build
Choose between FDU (V/Hz) and VFX (Direct torque control) versions. A VSI unit consists of a 3-phase igbt-bridge, DC-capacitor link, DC-fuses and a control unit. DC-connections are not required to be low-inductance and can be done with standard power cables for easy handling.
For your convenience, units exceeding 200kW feature multiple parallel PEBBs (Power Electronic Building Blocks), ensuring tailored and optimal performance to meet your specific needs.
