<p>There is described an electronic converter for supplying a lamp (L) or the like, comprising a thermal protection circuit (51) with a heat-sensitive component (63; 64) which senses a working temperature and cuts off the converter when the said working temperature exceeds a pre-set upper threshold value. Characteristically, the heat-sensitive component (63; 64) is inserted into a heat-sensitive block (53) with which is associated a feedback and thermal hysteresis block (57), which maintains the converter in the cutoff condition until the said working temperature reaches a lower threshold value. <IMAGE></p> |
