Title:
VOLTAGE CONVERSION CIRCUIT OF INTEGRATED VEHICLE-MOUNTED CHARGER
Document Type and Number:
WIPO Patent Application WO/2021/003648
Kind Code:
A1
Abstract:
Disclosed by the embodiments of the present application are a voltage conversion circuit of an integrated vehicle-mounted charger; an input circuit is connected to a first end of a magnetic element, and the second end of the magnetic element is connected to an output circuit; a first sub-input circuit is connected in series to a second sub-input circuit, the first sub-input circuit is respectively connected to a first port and a second port of the primary winding of the magnetic element, and the second sub-input circuit is respectively connected to a third port and a fourth port of the primary winding of the magnetic element; the first and second sub-input circuits generate first and second voltage signals, respectively, on the basis of an input high-voltage signal; first and second voltage signals generate first and second magnetic fluxes, respectively, in the same direction in the magnetic element; a third magnetic flux superimposed by the first and second magnetic fluxes generates induced electromotive force by means of the secondary winding of the magnetic element; the induced electromotive force generates a low-voltage signal by means of the output circuit. Using the embodiments of the present application can increase the adaptation range of the input voltage of the circuit.
