<p>A power converter (1) converts input power to a prescribed AC power and outputs the AC power to pairs of power lines (31, 32, 38, 39), and supplies the AC power to a load connected to the pairs of power lines. The pairs of power lines are positioned side by side on a main substrate (20), and island-like conductive regions (33a to 33d), which are connected to ground potential levels, are formed between the pairs of power lines. A first capacitor (C1) is connected to one of the power lines (31, 43) and to the island-like conductive regions via through-holes. A second capacitor (C2) is connected to the other power lines (32, 39) and to the island-like conductive regions via through-holes. The island-like conductive regions are connected to the ground potential levels. The present invention provides a power converter in which noise that is superimposed on a pair of current lines is attenuated.</p> |
