A power converter, comprising:
- a power supply unit provided with a first wiring and a second wiring and configured to apply a driving voltage to a load, the power supply unit being configured to adjust a magnitude of the driving voltage in response to a turn ratio of the first wiring to the second wiring;
- and
- a control unit configured to output a control signal for control the turn ratio of the first wiring to the second wiring based on the magnitude of the driving voltage.
A power converter, comprising:
- a first wiring through which an electric current flows in response to an input voltage;
- a first sub-wiring to which a driving voltage is induced according to a variation in the electric current flowing through the first wiring;
- a second sub-wiring to which the driving voltage is induced according to the variation in the electric current flowing through the first wiring;
- a third sub-wiring to which the driving voltage is induced according to the variation in the electric current flowing through the first wiring;
- a fourth sub-wiring to which the driving voltage is induced according to the variation in the electric current flowing through the first wiring;
- a first switch connected between the other terminal of the first sub-wiring and one terminal of the second sub-wiring;
- a second switch connected between the other terminal of the third sub-wiring and one terminal of the fourth sub-wiring;
- a first diode connected between one terminal of the first sub-wiring and an output terminal;
- a second diode connected between the first switch and the output terminal;
- a third diode connected between the second switch and the output terminal;
- a fourth diode connected between the other terminal of the fourth sub-wiring and the output terminal;
- and
- a control unit configured to output a first control signal for controlling turn-on or turn-off operations of the first switch and the second switch.
A power supply method of determining a driving voltage to be applied to a load based on a turn ratio of a first wiring to a second wiring, the method comprising;
- comparing the driving voltage with a reference voltage;
- and
- adjusting the turn ratio of the first wiring to the second wiring by blocking a flow of a driving current to a portion of the second wiring based on the comparison result between the driving voltage with the reference voltage.
