Abstract:

In order to ensure the high-speed generator running with wide voltage regulation capability to realize the generator variable speed regulated output, a hybrid excitation generator was studied, which adopts double-winding redundant structure design, two sets of windings which can work independently at the same time, and can realize dual channel load output. The working principle of the motor and the structure winding design were analyzed, simulations of the load switching process were conducted, the prototype was made to verify simulation results, and the voltage regulation performance was tested under different loads and different speeds.The experimental results show that the motor load meets the requirements of smooth operation of the dead-side working channel, and can provide stable DC power supply when the load or speed changes.

Key words: hybrid excitation generator, double winding structure, load switching, variable speed constant voltage output
