Abstract
A system for connecting a single-phase generator in parallel with an inverter is disclosed. A signal corresponding to the angular position of the rotor in the generator is provided to the inverter, for example, from an angular position sensor connected to the rotor in the generator. Because variations in the load applied to the generator cause variations in the frequency of the power output by the generator, the inverter synchronizes the phase angle of the voltage output by the inverter to the angular position of the rotor.
