Controller of electric vehicle

A controller of an electric vehicle capable of reducing the total sum of the loss of an AC motor and the loss of a main circuit. A vector control command value operating section (11a) calculates and selects a flux command value (F2R) and a DC voltage command value (EFCR) in response to a torque comm...

Beschreibung
Zusammenfassung:	A controller of an electric vehicle capable of reducing the total sum of the loss of an AC motor and the loss of a main circuit. A vector control command value operating section (11a) calculates and selects a flux command value (F2R) and a DC voltage command value (EFCR) in response to a torque command (T*) such that the total sum of the loss of an AC motor (1) and the loss of a second main circuit (7) is minimized. The vector control command value operating section (11a) outputs the flux command value (F2R) to a vector control section (8) and outputs a DC voltage command value (EFCR) to a converter control section (6).
