PURPOSE:To control to allow a power source current to follow its command value faithfully by constructing to eliminate the influence of the disturbance of the power source voltage inputted to a power source current control system. CONSTITUTION:When an actual current Ic has a relationship of Ic*>Ic to the output current command value Ic* of a converter, a deviation epsilon1=Ic*-Ic becomes positive value, thereby increasing one ei of the input signal of a pulse width modulation control through a control compensator G1(S). Thus, the output current Ic of the converter is increased, and the current Ic is controlled to bring into coincidence with the value Ic*. On the contrary, when becoming Ic*< Ic, the current Ic decreases, and is controlled be bring into coincidence with the value Ic*. In this case, the voltage VL applied to an AC reactor Ls relates only to the deviation epsilon1=Ic*-Ic, and is not affected by the influence of the current voltage Vs. |
