PURPOSE: To provide a controller for an AC-DC converter which can stably operate DC system by cutting off the loop of vicious cycle where harmonic waves are unstable even if the state of AC system changes. CONSTITUTION: This controller of an AC-DC converter is equipped with a state detection means 41, which detects the change of the state of an AC system, a memory 42, which stores the control parameter of a constant current control means geared to the state of the AC system, and a parameter change means which changes the control parameter of the constant current control means into the specified value stored in the memory 42, by the output of the state detection means 41. |
