摘要： A high-frequency large current handling transformer includes a stack of plural metal planar coil members with a window formed in a center portion of each of the planar coil member. A slit extends outward from the window in each planar coil member. First and second terminals are provided for each planar coil member at locations on opposite sides of the slit. An insulating sheet having a window formed in its center portion is disposed between adjacent ones of the planar coil members. Some of the planar coil members are connected in series to provide a higher-voltage side coil, and the remaining planar coil members are connected in parallel to provide a lower-voltage side coil. An 8-shaped high-frequency core is operatively combined with the coils.

摘要： A voltage from an AC power source is converted into a DC voltage in an input-side rectifier-smoother circuit. The DC voltage is then converted into a high-frequency voltage in an inverter, and the resulting high-frequency voltage is voltage-transformed in a transformer. The voltage-transformed high-frequency voltage is converted into a DC voltage in an output-side rectifier-smoother circuit, which is applied via output terminals to a load. The input-side and output-side rectifier-smoother circuits, the inverter and the transformer are enclosed in a casing having a plastic panel. The output terminal of the apparatus is mounted on the plastic panel. When a temperature sensing unit with a temperature sensor disposed on the panel near the output terminal senses that the temperature of the panel has risen above a predetermined temperature, which is lower than the heat deformation temperature of the panel, a gate signal ON-OFF circuit prevents a gate signal from a gate signal generating circuit from being coupled to the inverter. The gate signal ON-OFF circuit permits the gate signal to be coupled to the inverter when the temperature sensing unit senses that the temperature of the panel has decreased below the predetermined temperature.

摘要： A power supply apparatus includes first and second spaced-apart, substantially parallel panels, and a chassis disposed in substantially perpendicular to and between the first and second panels. Opposite edges of the chassis are coupled to the respective ones of the first and second panels to thereby partition the space between the first and second panels into upper and lower regions. A power supply circuit includes heat-generating electric components disposed in the lower region, and non-heat-generating components disposed in the upper region. The chassis has an opening therein and a heat sink is mounted to close the opening in the chassis. A semiconductor module of the power supply circuit is mounted on the surface facing to the upper region of the heat sink.

摘要： An air plasma arc cutter includes spaced apart front and rear panels. A partition wall has its opposed two edges coupled to the front and rear panels to divide the space therebetween into upper and lower regions. An AC-to-DC voltage converter is disposed in the upper region and converts an AC voltage to a DC voltage to be applied between a torch electrode of a torch of the cutter and a workpiece. An air compressor supplies compressed air around the torch electrode and is disposed in the lower region. The air compressor has a threaded bolt which extends through the partition wall from the lower into upper regions. A nut is screwed onto the bolt in the upper region to thereby secure the air compressor to the partition wall. Shock absorbing members are disposed between the nut and the partition wall and between the air compressor and the partition wall.
