Beschreibung
Zusammenfassung:	Provided is a vehicle direct current voltage conversion circuit, comprising a high voltage battery (10), a primary side bridge module (20), a resonant module (30), a transformer module (40), and a secondary side output module (50) that are connected in sequence, wherein the secondary side output module (50) comprises a first voltage unit (51) that outputs a first voltage and a second voltage unit (52) that outputs a second voltage, and a secondary side winding of a transformer is connected to the first voltage unit (51) and the second voltage unit (52), respectively. The circuit further comprises a driving module (60) connected to the primary side bridge module (20). The vehicle direct current voltage conversion circuit can not only output a first voltage but also simultaneously output a second voltage, has the advantages of a small volume, high efficiency, low cost and industrialization, and can be widely applied to vehicle 48 V electrical appliance loads, for example, devices such as a 48 V vehicle electric
