Abstract: In an isolated gate driver system, isolation for both power transmission and signal transmission is integrated into a single module. The isolated gate driver system includes a resonant isolated DC-DC converter, and uses a modulation scheme to transfer a control signal in combination with power supply through a transformer of the resonant isolated DC-DC converter. A resonance tank control switch modifies a capacitance in a resonance tank circuit based on a signal indicative of the control signal.

Abstract: A device includes a substrate; a magnetic core in the substrate, including a hole, and divided into a first half and a second half opposite to the first half; a first winding extending through the hole and around the magnetic core; a second winding extending through the hole and around the magnetic core; and a third winding extending through the hole, around the magnetic core, and around a portion of the first winding. The first and the third windings only extend around the same half of the magnetic core. At least one first turn of the second winding extends around the second half of the magnetic core.

Abstract: An inductor component includes cores, a coil disposed in the cores, and terminal electrodes. The coil includes first metal plates disposed on an upper surface of the cores, second metal plates disposed on a lower surface of the cores, and a plurality of metal pins each passing through one of the cores in a thickness direction. The coil has a helical shape by connecting the first metal plates to the second metal plates, with the plurality of metal pins therebetween. The terminal electrodes are spaced apart along a direction in which the helical shape extends, and are connected to the coil.

Abstract: A DC-DC conversion circuit includes an input voltage; a half-bridge circuit connected to the input voltage and including a first leg with first, second, third, and fourth switching elements connected in series and including a second leg with first and second capacitors connected in series with each other and connected in parallel with the first leg; and a flying capacitor connected to a node between the first switching element and the second switching element and a node between the third switching element and the fourth switching element; a transformer including a primary winding connected to the half-bridge circuit; and a controller that controls the first to fourth switching elements. The controller selectively controls the half-bridge circuit in a half-bridge operation in which ±Vin/2 is applied to the primary winding, where Vin is the input voltage and a 3-level half-bridge operation in which ±Vin/4 is applied to the primary winding.
