  • DC/DC boost converter
    Patent number: 8513932
    Abstract: A DC/DC boost converter includes a first boost driving unit, a second boost driving unit connected in parallel with the first boost driving unit, and a capacitor electrically connected to the first and second boost driving units. The first boost driving unit is utilized for performing a first driving operation according to an input voltage and a first control signal. The first driving operation includes a first energy-storing operation and a first energy-releasing operation. The second boost driving unit is utilized for performing a second driving operation according to the input voltage and a second control signal different from the first control signal. The second driving operation includes a second energy-storing operation and a second energy-releasing operation. The first and second energy-releasing operations are employed to alternately charge the capacitor for generating an output voltage.
