Beschreibung
Zusammenfassung:	A voltage converter includes a conversion unit, a self driver and an output unit. The conversion unit includes at least one inductor and provides a boosting power based on an input voltage and a first driving signal. The self driver includes at least one inductor that forms a magnetic coupling with the at least one inductor of the conversion unit. The self driver generates a second driving signal that is synchronized with the first driving signal through the magnetic coupling. The output unit generates an output voltage based on the boosting power and the second driving signal. Switching loss and conduction loss may be reduced by replacing an output diode with an output transistor and voltage spike and electromagnetic interference may be reduced through zero voltage switching. The driving signal of the output transistor may be controlled efficiently by adjusting the inductance of the driving inductor.
