Kind Code:
B2
Abstract:
PURPOSE:To prevent a fluctuation voltage component that could be caused by a fluctuation load when the fluctuation load whose impedance fluctuates at a specified period is used as a load. CONSTITUTION:A first resonance filter circuit 21 which is constituted of a serial combination of a first inductance element 22 and a first capacitance element 23 and which resonates at the frequency of a fluctuation voltage component is connected in parallel with a capacitor for filter 5 of a smoothing filter circuit 3. By this method, the input voltage of an inverter can be kept constant without being influenced by the fluctuation voltage component and thereby the operation of a constant-voltage control system can be kept stable and at the same time, the fluctuation voltage component is prevented from flowing out to the dc supply side and as a result, there is no bad influence on a signal equipment, etc.
