<p>PURPOSE: A single-stage isolated high power factor AC/DC converter is provided to simplify a circuit structure by integrating a PFC(Power Factor Correction) circuit with a power conversion circuit. CONSTITUTION: A buck-boost circuit(230) step down or up power. An input capacitor is electrically connected to the buck-boost circuit. A transformer is electrically connected to the buck-boost circuit to convert the stepped-down or up power. A switch is electrically connected to the buck-boost circuit. An output circuit(240) outputs the power transformed by the transformer.</p> |
