Description
technical field [0001] The invention relates to the field of generators, in particular to a generator with a variable circuit rectifier bridge. Background technique [0002] The electrical connection of the traditional generator stator assembly is a delta delta or star Y connection. In electrical engineering, three-phase alternating current is generally a variable voltage passing through three different sets of conductors. These three sets of voltages have equal amplitudes, equal frequencies, and a phase difference of 120 degrees between them. The traditional delta-connected generator realizes this connection through fixed embedding wires in the stator or rectifier bridge bracket. This connection can output more current at higher speeds, but at low speeds, the output capacity is limited. Suppress low output efficiency; traditional star-shaped Y-connection generators realize this connection through fixed embedded wires in the stator or rectifier bridge bracket. This connect...
