摘要： A power electronics module includes a printed circuit board populated with numerous components of the power electronics module. Power semiconductors and DC and AC connecting elements are either placed adjacently to one another on an organic insulator, and each thermally and mechanically connected to a heat sink through the organic insulator, or the DC and AC connecting elements are placed between the power semiconductors and the heat sink and are thermally and mechanically connected to the heat sink and to the power semiconductors.

摘要： A symmetrical DC-to-DC boost converter includes a DC input voltage source with a negative DC voltage input and a positive DC voltage input, a negative DC and positive DC voltage output, at least four switches, and two chokes, one of which is connected to the negative DC voltage input and two adjacent switches, and the other of which is connected to the positive DC voltage input and two other adjacent switches, such that a symmetrical topology with separate DC voltage inputs is obtained. Furthermore, there is an input capacitor between the voltage inputs and a first symmetry capacitor connected to the negative DC voltage input and the negative DC voltage output, as well as a second symmetry capacitor connected to the positive DC voltage input and the positive DC voltage output.

摘要： A symmetrical DC-to-DC boost converter includes two magnetically coupled chokes, of which one choke is connected to a negative DC voltage input in the DC-to-DC boost converter, while the other choke is connected to a positive DC voltage input in the DC-to-DC boost converter, such that a symmetrical topology is obtained with separate DC voltage inputs, wherein the coupled chokes have three cores in a series, each of which is connected at the top and bottom to a connecting core, and there is at least one winding on each of the two outer cores that is dedicated to one of the chokes, while the middle core does not have a winding, and has at least one air gap and/or is at least partially made of a low permeability powdered material, and therefore forms a magnetic energy storage.

摘要： In a half-bridge module for an inverter, semiconductor switches and signal and power connections are arranged on a first surface of a substrate and coated with a casting compound, and external connection contacts for the signal and power connections extend through the casting compound to the exterior. In various embodiments, the external connection contacts extend from the casting compound from four second surfaces that are orthogonal to the first surface, and have a first right angle bend outside the casting compound, such that the ends of the external connection contacts are perpendicular to the first surface. The invention also relates to a corresponding inverter.

摘要： A half-bridge includes a substrate, semiconductor switches, power connections and signal connections. The power and signal connections are formed in a flat conductor frame. The signal connections are electrically connected to the semiconductor switches such that they can be switched via the signal connections and the power connections are electrically connected to the semiconductor switches such that they allow or interrupt electricity transfer between the power connections. The semiconductor switches, signal connections, and power connections are on a first surface of the substrate in a casting compound. First end sections of the signal connections formed in the flat conductor frame each extend from a second surface orthogonal to the first surface, exiting the casting compound. Second end sections of the signal connections, which are separate from the flat conductor frame, are connected to the first end section outside the casting compound and are perpendicular to the first surface.
