    摘要: An electronic control device includes a heating element, a circuit substrate, a heat radiation plate, and a heat radiation material. Connection terminals of the heating element are fixed to wiring patterns on a circuit principal surface of the circuit substrate with solder. Through holes are provided in the circuit substrate at portions spaced away from the distal ends of the connection terminals of the heating element by a distance equal to or smaller than a thickness of the circuit substrate. The heat radiation material applied between a circuit principal surface of the circuit substrate and the heat radiation plate is exposed to the circuit principal surface via the through holes. The heat radiation material exposed to the circuit principal surface covers the distal ends of the connection terminals fixed with the solder.

    摘要: In accordance with presently disclosed embodiments, a system and method for controlling the temperature of medium-voltage power electronics assemblies (i.e., medium-voltage drives) is provided. The disclosed system generally includes a medium-voltage drive having one or more cabinets with power electronics devices disposed therein, one or more fans for circulating air through the cabinet to cool the devices, and one or more space heaters disposed in the cabinet. The drive also features temperature sensors used to measure various temperatures of the drive, a controller communicatively coupled to the sensors, and one or more variable frequency drives (VFD) for the fans. The controller may receive measurements regarding the ambient and power device temperatures and apply controls to vary the space heater power and fan speed in response to environmental changes.

    摘要: A first printed circuit board on which a heatsink having a discrete semiconductor device attached to it and first capacitors for smoothing an electric current after a conversion from AC to DC are mounted is arranged in the horizontal direction of a bottom portion of a device casing. On the first printed circuit board, various electronic components such as a resistor, a diode, a capacitor, a coil, etc. are mounted in addition to the heatsink and the first capacitors. Further, in an in-device-casing vacant space in an upper portion of the heatsink mounted on the first printed circuit board, a second printed circuit board on which second capacitors for performing smoothing upon a conversion from AC to DC are mounted is arranged orthogonally to the first printed circuit board in the device spacing.

    摘要: An inverter for converting an input-end direct current into an output-end alternating current to be fed into an AC voltage supply system includes a first housing part with direct current connections for receiving direct current lines of a direct current generator, a second housing part with alternating current connections for receiving alternating current lines of an AC voltage supply system, a third housing part for accommodating power-electronics components of a DC voltage converter, and a fourth housing part for accommodating power-electronics components of an inverter bridge circuit. The housing parts each have an essentially planar rear wall and are arranged in such a way that they enclose a cooling-air duct with an essentially rectangular cross section, wherein the first housing part is arranged opposite the second housing part and the third housing part is arranged opposite the fourth housing part. The inverter also includes a heat sink, which has two essentially planar cooling faces opposite one another arranged in the cooling-air duct, wherein the cooling faces are assigned to the rear walls of the third housing part and the fourth housing part and are in thermal contact with power-electronics components arranged in these housing parts.
