Abstract
The utility model relates to a middle-point-connected-with-capacitor circuit for a split rotor magnetic flux switching double salient pole direct current generator. The middle-point-connected-with-capacitor circuit for a split rotor magnetic flux switching double salient pole direct current generator is characterized in that three phase armature windings A, B, and C of the split rotor magnetic flux switching double salient pole direct current generator are in star connection and therefore a winding middle point 0 is formed, two capacitors C1 and C2 are connected in series on a split capacitor branch, and a connecting point of the capacitors C1 and C2 is connected with the electromotor winding middle point 0. Ends of the three phase armature windings A, B, and C are connected with a filter capacitor C3 through a full bridge uncontrolled rectification circuit and therefore power is supplied to a load Z0, wherein the ends of the three phase armature windings A, B, and C are not connected with the middle point; and the full bridge uncontrolled rectification circuit consists of D1, D2, D3, D4, D5, and D6. When the middle-point-connected-with-capacitor circuit is used for an electric generator, the electric generator at the same excitation power is characterized by hard external characteristics, high power factors and increased maximum value of the electricity generating power, and therefore power density of the double salient pole direct current generator is remarkably improved. Because the split capacitor branch is connected with the rectification circuit in parallel, the middle-point-connected-with-capacitor circuit is advantaged by compensating function, filtering effects, and capability of effectively reducing capacity of the filtering capacitor.
