Title:
界磁巻線型同期電動機
Document Type and Number:
Japanese Patent JP6596358
Kind Code:
B2
Abstract:
A field winding type synchronous machine connects to a DC line and includes a rotor; a stator; an exciter that passes a current through a field winding of the rotor; and a rectification circuit that rectifies an output from the exciter and provides the output to the DC line. The synchronous machine includes the field winding being connected in parallel to a first circuit in which a parallel circuit including a rectifier element and a first switchgear is connected in series to a discharge resistor, a second switchgear being connected in series to the DC line that connects the first circuit to the rectification circuit, and a capacitor being provided between the discharge resistor and the input side of an electric power source element for gating the first switchgear.
