The present document relates to power converters. A power converter may be configured to convert an input voltage at an input of the power converter into an output voltage at an output of the power converter. The power converter may comprise a first switching circuit with a first inductor, a first high-side switching element, and a first low-side switching element. The power converter may comprise a second switching circuit with a second inductor, a second high-side switching element, and a second low-side switching element. The power converter may comprise a capacitive element having a first terminal coupled to the first high-side switching element and to the second high-side switching element and having a second terminal coupled to the first low-side switching element at a first node. The power converter may comprise a third switching element coupled between the first node and the output of the power converter.

Multi-mode two-phase buck converter

The present document describes a power converter configured to provide energy at an output based on energy provided at an input. The power converter comprises a first switch, wherein a first node is coupled to the input and wherein a second node is coupled to an intermediate point, a second switch, wherein a first node is coupled to the intermediate point and wherein a second node is coupled to an inductor point, a capacitor, wherein a first node of the capacitor is coupled to the intermediate point, a first diode element, wherein a first node is coupled to a second node of the capacitor and wherein a second node is coupled to the inductor point, a second diode element, wherein a first node is coupled to a reference port, and wherein a second node is coupled to the second node of the capacitor; and an inductor, wherein a first node is coupled to the inductor point and wherein a second node is coupled to the output.

Power converter with a high conversion ratio

A switching power converter includes an integrated transformer and coupled inductor, first and second primary switching circuits, and a master controller. The integrated transformer and coupled inductor includes (a) first and second primary windings electrically coupled in series and (b) first and second secondary windings. The first and second primary switching circuits are electrically coupled to an end of the first primary winding and an end of the second primary winding, respectively. The master controller is configured to determine a magnitude of magnetizing current of the integrated transformer and coupled inductor from a difference between magnitude of current flowing through the first secondary winding and magnitude of current flowing through the second secondary winding, when the first and second primary switching circuits are in their respective off-states.
