Abstract

The invention provides a DC / DC device. The DC / DC device comprises a self-excited oscillator, a first transformer, a first mos transistor, a second mos transistor, a third mos transistor, a fourth mos transistor, a first capacitor and a second capacitor, wherein the self-excited oscillator comprises a second transformer, and the second transformer of the self-excited oscillator comprises a first angle, a second angle, a third angle, a fourth angle, a fifth angle, a sixth angle, a seventh angle, an eighth angle, a ninth angle and a tenth angle; the self-excited oscillator generates a high-frequency sine wave signal to allow the first mos transistor, the second mos transistor, the third mos transistor and the fourth mos transistor to obtain completely-symmetrical sine wave drive voltage, alternating voltage is output through the isolation and transformation by the transformers, the alternating voltage is turned into direct-current voltage through the second capacitor, and the direct-current voltage is output. By the DC / DC device applicable to low-voltage DC / DC, each device can work under extremely low voltage through the completely-symmetrical sine wave drive.
