The present invention relates to a resonance-type DC-DC converter comprising: a transformer to supply output voltage of values converted for input voltage in accordance with winding ratios of a first, a second, and a third coil; a first bridge circuit part which has multiple switching devices, is connected to a coil at a first side of the transformer and is applied with a power source; a second bridge circuit part which is connected to a coil at a second side of the transformer and is applied with inductive voltage in accordance with winding ratios of a first side coil and a third side coil to output DC voltage; and a resonance part serially connected to a third side coil of the transformer. According to the present invention, the converter has an advantage of being appropriate for converter application since the converter has a broad voltage variation with a small frequency variation in accordance with voltage variation. |
