Abstract
It is presented a power converter for transferring electric power provided on an input terminal to an energy storage element. The power converter comprises: an inductor; a switch connected to selectively control a connection between the inductor and the input terminal; and a comparator, wherein an output of the comparator controls the switch, a first input of the comparator is supplied with a voltage being proportional to a voltage of the input terminal, and a second input of the comparator is supplied with a voltage being proportional to a current from the input terminal; wherein the energy storage element is connected to a point between the inductor and the switch.
Claims13
A power converter for transferring electric power provided on an input terminal to an energy storage element, the power converter comprising:
- an inductor;
- a diode;
- a switch connected to selectively control a connection between the inductor and the input terminal;
- and
- a comparator, wherein an output of the comparator controls the switch, a first input of the comparator is supplied with a voltage being proportional to a voltage of the input terminal, and a second input of the comparator is supplied with a voltage being proportional to a current from the input terminal when the switch is closed, whereby the current from the input terminal and the voltage of the input terminal vary proportionally;
- wherein the energy storage element is connected on one end, via the diode, to a point between the inductor and the switch and the energy storage element is connected on the other end to ground, such that an anode side of the diode is connected to the energy storage element and a cathode side of the diode is connected to the point between the inductor and the switch.
