­During their extensive service life, low-power transformers are subjected to a wide variety of stress. The electrical insulation, which is essential for fault-free operation, can be damaged as a result. Despite taking the utmost care, small defects, cavities, cracks, inclusions in the dielectric, or inhomogeneities in

Figure 1: Multiple outputs using non-isolated DC-DC converters with fixed polarity outputs

­The outputs for multiple output power supplies could be fixed at +5V, +12V and -12V for example, sharing a common 0V terminal with no isolation between the outputs. Other types of power supplies, on the other hand, may have one, two, or all three of the outputs isolated from each other. But are there any benefits of
