摘要： An energy combiner apparatus is used to convert output of a power supply, and has three output terminals, so that output ports are increased. In the three output terminals of the energy combiner apparatus, a voltage of 1500 V is output between a first output terminal and a second output terminal, a voltage of 1500 V is also output between the second output terminal and a third output terminal, and a total of 3 kV is output. Therefore, an overall output voltage is increased in a case of equal output power. Because the overall output voltage is increased, a current transmitted on a cable may be reduced. Therefore, a thinner cable may be used, so that costs of the cable are reduced. In addition, four cables conventionally required for connecting to the output terminals of the energy combiner apparatus are reduced to three, so that quantity and costs are reduced.

摘要： A power converter may comprise a magnetic core, a transformer primary winding configured to generate a magnetic field in the magnetic core, and a transformer secondary winding matrix. The transformer secondary winding matrix may comprise a plurality of secondary windings configurable between various electrical connections relative to one another (e.g., in series or in parallel) to adjust a voltage conversion ratio of the power converter.

摘要： The design of high-power RF amplifiers, specifically the design of the output transformer, is complicated by the relatively low voltage provided by battery packs that are practical for handheld devices meant for possibly delicate uses. Provided is an RF amplifier with one or more taps on the primary coil, wherein each tap is controlled by a half bridge driver. The output transformer primary winding may be driven between any two half bridge drivers, with the number of turns between the half bridge drivers and the fixed output winding determining the overall turns ration for the transformer.

摘要： An embedded magnetic component transformer device includes an insulating substrate with a cavity and a magnetic core housed within the cavity. First and second electrical windings pass through the insulating substrate around the magnetic core. The first electrical winding includes a first end terminal and a second end terminal, and a first tap terminal between the first and second end terminals. The device includes circuitry with a first input terminal electrically connected to the first end terminal and a first output terminal. In a first configuration of the circuitry, the first output terminal is electrically connectable to the second end terminal. In a second configuration of the circuitry, the first output terminal is electrically connectable to the first tap terminal.
