Abstract
An on-vehicle power supply device is connected to a vehicle battery with revealing. The on-vehicle power supply device is used for receiving a DC input power supplied by the vehicle battery, and the on-vehicle power supply device induces a plurality of high-frequency voltages through a single isolation transformer at the same time, and then transforms the high-frequency voltages to produce at least one AC output voltage and DC output voltage. In addition, the on-vehicle power supply device further includes a rechargeable battery. The rechargeable battery can be charged when the DC input power is importing. When the DC input power stops importing, the rechargeable battery is used for supplying a backup power to the isolation transformer, and the rechargeable battery keeps producing AC output voltage and DC output voltage. Hence, the present invention can achieve the effects of multipurpose, safety, and continuity.
