A surge protection circuit comprises a bridge rectifier having two input terminals coupled to an input source of electricity that may experience highly positively or negatively biased over-voltage and/or over-current, and two output terminals respectively coupled to a voltage surge blocking stage via a first bus line and to a return bus; a current surge protection stage that is series coupled in the first bus line between the voltage blocking stage and a voltage surge detection stage that is disposed between the first bus line and the return bus; two output terminals respectively coupled to the first bus line and the return bus, after the current surge protection stage. Embodiments can protect circuits or apparatus, such as DC-DC converters, that are sensitive to highly positively or negatively biased voltage/current surges by inverting negative pulses associated with a surge and outputting the inverted or rectified over-voltage/over-current to other protection circuitry. During events such as lightning strikes, apparatus such as DC-DC converters are effectively transiently powered by the strike, from which negative bias has been removed and passed through blocking and surge protection stages.
