AN ISOLATED SINGLE SWITCH RESONANT CONVERTER AND AN ISOLATED INTERLEAVING SINGLE SWITCH RESONANT CONVERTER USING THE SAME

摘要

Disclosed is a single switch insulation type resonance converter including a single switch device. The single switch insulation type resonance converter comprises: a filter inductor connected to a positive input terminal; a clamping capacitor connected to a negative input terminal; a transformer having a first coil connected between the filter inductor and the clamping capacitor and a second coil corresponding to the first coil; a switch device to be controlled by a switch control signal by being connected between the filter inductor and the negative input terminal; a rectifier for rectifying the voltage from the second coil of the transformer; a voltage doubler filtering and boosting the voltage rectified by the rectifier; and a resonant tank providing the rectifier to perform zero current turn-off operation by being connected between the rectifier and the second coil of the transformer.
