| 摘要 |
<p>This is an insulation-type power factor correction circuit including a resonance unit configured to accumulate energy of a surge occurring when the first switching element is turned off and to transmit a resonance current generated by resonating the first capacitor and the primary winding of the second transformer from the primary winding of the second transformer to the secondary winding, a rectifier unit configured to rectify a resonance current output from the resonance unit, a smoothing unit configured to regenerate power output from the rectifier unit to an output of the insulation-type power factor correction circuit, and a control unit configured to control a first switching element for each cycle.</p> |
