<p>The object of the invention is to provide a DC-DC converter that facilitates preventing switching noises, caused by the switching of a main switching transistor and its driver, from affecting the control circuit (3) adversely and securing stable operations of the converter. The DC-DC converter according to the invention includes a feed line (LS1) for the main circuit, a ground line (LG1) for the main circuit, a positive feed line (LS2) for the control circuit, a negative feed line (LG2) for the control circuit (3), an insulation resistance (Rd1) connected to the feed line (LS1) or to the feed line (LS2), (or) an insulation resistance (Rd2) connected to the ground line (LG1) or to the feed line (LG2), and, if necessary, a filter capacitor (Cd) connected in parallel to the control circuit (3). <IMAGE></p> |
