Abstract
A buck-boost power conversion circuit comprises a first active switch, a second active switch, an inductor, a center-tapped current transformation element, and a signal rectification unit. The first active switch is cascaded to the second active switch, which is connected in parallel with a power source. The inductor is connected with a capacitor. The center-tapped current transformation element includes a primary winding and a secondary winding. The primary winding are connected with the first and second active switches. The primary winding includes a tapped terminal connected with the inductor. While the first or second active switch is turned on, the primary winding supplies power to the inductor through the tapped terminal, and the secondary winding is induced magnetically to generate a magnetic induction signal. The signal rectification unit is connected with the secondary winding, receiving and rectifying the magnetic induction signal to generate a current sensation signal.
