Abstract: A multi-phase coupled inductor includes a first iron core, a second iron core, and a plurality of coil windings. The first iron core includes a first body and a plurality of first core posts. The plurality of first core posts are connected to the first body. The second iron core is opposite to the first iron core. The second iron core and the first body are spaced apart from each other by a gap. The plurality of coil windings wrap around the plurality of first core posts, respectively. Each of the coil windings has at least two coils.

Abstract: A portable electronic device, an operating method for the same, and a non-transitory computer readable recording medium are provided. The portable electronic device includes a body, a touch display screen and an edge sensor. The touch display screen is disposed on the body. The edge sensor is disposed adjacent to an edge of the body. The operating method includes the following step. When an event is generated according to a first action sensed by the edge sensor, a touch function of a region of the touch display screen or the whole touch display screen is disabled.

Abstract: A portable electronic device, an operating method for the same, and a non-transitory computer readable recording medium are provided. The portable electronic device includes a body and an edge sensor disposed adjacent to an edge of the body. The operating method includes the following step. When a plugging-in event or a plugging-out event of a peripheral device is detected by the portable electronic device, a squeezing event sensed by the edge sensor is ignored. The squeezing event may be generated when a squeeze action sensed by the edge sensor occurs during a first time period. The plugging-in event or the plugging-out event may occur during the first time period. Alternatively, the squeeze action may begin within a second time period after the plugging-in event or the plugging-out event occurs.

Abstract: A circuit used to convert DC input to AC output comprises a transformer and three series sub-circuits. The first series sub-circuit is connected in parallel with the DC input and comprises first and second capacitors connected in series. The secondary series sub-circuit is connected in parallel with the DC input and comprises a first primary winding of the transformer, a clamping capacitor and a second primary winding of the transformer sequentially connected in series. The third series sub-circuit connected in parallel with said clamping capacitor and comprises first and second switches connected in series. The center nodes of the first and third series sub-circuits are connected together. Thus, while a secondary winding of the transformer provides AC voltage, the circuit is able to effectively reduce current ripple and decrease voltage stress on semiconductor switch with minimum component count. Similar topologies may be used for rectification instead of inversion.
