Abstract
A boost converter circuit able to sense current comprises an inductor connected with a power source; an active switch; a passive switch; a capacitor connected with one end of the passive switch, which is not connected with the active switch; a center-tapped current transformation element; and a signal rectification unit. The center-tapped current transformation element includes a primary winding and a secondary winding. Two ends of the primary winding are respectively connected with the active switch and the passive switch. The primary winding is connected with the inductor through a tapped terminal. The secondary winding is magnetically induced by the primary winding to generate a magnetic induction signal while the primary winding receives an inductor current. The signal rectification unit is connected with the secondary winding, receiving the magnetic induction signal and rectifying the magnetic induction signal to generate a sensed current signal corresponding to the inductor current.
