<p>The present invention relates to an insulation type switching mode power supply. An insulation type switching mode power supply according to an embodiment includes a power source part which supplies DC power, a conversion part which transforms a voltage received from the power source part, a pulse conversion part which changes a voltage transformed by the conversion part into a pulse signal, a rectification part which rectifies a pulse signal outputted from the pulse conversion part, an output part which outputs a voltage rectified by the rectification part, a resonance capacitor part which is connected between the power source part and the pulse conversion part, and a resonance inductor part which is connected between the pulse conversion part and the rectification part. The resonance capacitor part and the resonance inductor part form a resonance circuit. The insulation type switching mode power supply according to the embodiment can reduce the loss of the circuit by preventing the generation f a surge voltage and a switching restoration current.</p> |
