Abstract
A hipot barrier structure for a transformer for preventing instantaneous hipot from transiting from pins at high-tension side to pins at low-tension side directly via a conductive core of the transformer, so that damages to the whole circuitry can be avoided to comply with required safety code. The barrier structure includes a barrier member made of insulating material and having a generally C-shaped cross-section for fitly covering the high-tension side of the core in a tight fit relation and forming an outer layer of the core at the high-tension side. The barrier member increases a creepage distance between the pins and the conductive core and therefore effectively prevents a hipot from directly crossing over the core.
