Abstract
An LLC resonant converter in which a capacitor (Cr), an inductance (Lr), and a power line between the capacitor (Cr) and the inductance (Lr), which constitute a series resonance unit, are resin-encapsulated by a resin. Because the series resonance unit that is a high voltage portion is resin-encapsulated collectively, it is possible to shorten an insulation distance even in the case of higher voltages and frequencies, and to prevent an increase in size.
