The system consists of a permanent magnet generator and a single phase inverter to be applied to a generating set (with a gasoline engine)
As the application is in the domestic field, the stability and the quality of the generated voltage must grant the correct working and safety of electronic devices, computers, household appliances, etc.
Our aim is to realize a control system that grants a consistent inverter’s output voltage in presence of load variations. By, also, optimizing the engine performances adapting the speed in function of the output load. The fuel consumption and noise are dramatically reduced.
The generator has been realized with one three phase permanent magnet (NeFeBo) machine in order to obtain an high power density and reduced volumes; the stator’s winding is inside while the rotor runs outside.
For the generator’s dimensions see the table herewith enclosed.
The main inverter’s features are:
- Output voltage: 230V -50Hz single phase (60Hz on demand)
- THD: < 2%
- Max. continuous power: 10KW
- Max overload: 30-50% (depending on the engine) restricted in time
- Two of these devices can be linked in parallel to increase available wattage through the generator outlets.
- Performances following ISO8528 (generator-set): G4 / G3 class
