Abstract:
The disclosed technology can be used to convert direct-current voltage and current from an input to a different or the same voltage and current at an output. One example direct-current to direct-current (DC-DC) power converter includes a first switch connected between a source voltage and a first side of an inductor, a second switch connected between the first side of the inductor and a ground, a third switch connected between a second side of the inductor and the ground, and a fourth switch connected between the second side of the inductor and a capacitor. The power converter may further include a comparator configured to compare an output voltage at the capacitor to a threshold voltage and based on the result of the comparison selectively activate or deactivate the first, second, third, and fourth switches in a power cycle.

Claim (Index 23):
A method of power conversion using a direct-current to direct-current (DC-DC) power converter comprising a first a first, a second, a third and a fourth switch, the first switch connecting a first side of an inductor to a source voltage, the second switch connecting the first side of the inductor and a ground, the third switch connecting a second side of the inductor and the ground, and the fourth switch connecting the second side of the inductor and a capacitor, the method comprising:\n causing, at a first switching times that commences a first time interval, the first switch and the fourth switch to turn on and the second switch and the third switch to turn off, wherein during the first time interval current flows through the inductor to the capacitor thereby charging the capacitor and generating magnetic fields around the inductor; causing, at a second switching time that commences a second time interval, the second switch to turn on and the first switch to turn off while allowing the third switch to remain off and the fourth switch to remain on, wherein during the second time interval energy stored in the magnetic fields decreases while continuing to charge the capacitor; causing, at a third switching time that commences a third time interval, the fourth switch to turn off while allowing the first and the third switches to remain off and the second switch to remain on, wherein during the third time interval the capacitor is disconnected from the inductor; and causing, at a fourth switching time that commences a fourth time interval, the third switch to turn on while allowing the first and fourth switches to remain off and the second switch to remain on, wherein during the fourth time interval a residual energy in the inductor is shorted to the ground.
