Power converter with noise-current reduction capacitor

A power converter comprising:

• a housing that is grounded;
• a power converter circuit having a portion that generates AC magnetic field having a magnetic flux and configured to perform power conversion of input power into output power;
• an external terminal electrically connected to the power converter circuit for connection of an external device to the power converter circuit;
• a first capacitor having first and second electrodes, the first electrode being connected to the external terminal and the second electrode being connected to the housing;
• and
• a second capacitor having first and second electrodes, the first electrode being connected to the external terminal and the second electrode being connected to the housing,
• the first capacitor, the external terminal, the second capacitor, and the housing being arranged to provide a conductive loop having:
• a first region through which the magnetic flux of the AC magnetic field penetrates to induce a first noise current flowing through the conductive loop;
• and
• a second region through which the magnetic flux of the AC magnetic field penetrates to induce a second noise current flowing through the conductive loop,
• the first noise current flowing through the conductive loop being opposite in direction from the second noise current flowing therethrough.
