PURPOSE:To provide a high performance power converter which is composed of a digital control system and whose response is improved. CONSTITUTION:A power converter has a first proportional amplifier 61 which calculates a first calculation output signal showing the calculation result of a same phase digital voltage signal and a voltage instruction value signal, a second proportional amplifier 62 which calculates a second calculation output signal showing the calculation result of an orthogonal digital voltage signal and a voltage phase instruction value signal and a first integral circuit 63 which operates the integral calculation of the first calculation output signal. Further, a first holding circuit 65 which holds the calculation result of the preceding conduction control, a second integral circuit which operates the integration of the second calculation output signal and a second holding circuit 66 which holds the calculation result of the preceding conduction control are provided. |
