Abstract: A power module for a converter of electrical magnitudes having an electronic board on which a first electrical circuit is fashioned which defines a positive pole of a direct magnitude, a second electrical circuit is fashioned which defines a negative pole of a direct magnitude, and a third electrical circuit is fashioned which conducts an alternating magnitude. There is one or more first and second electronic switching devices arranged between the first and second electrical circuit, and the third electrical circuit so as to realize the conversion. The first and second electrical circuit are, at least for respective coupling portions, arranged in proximity to the electronic switching devices, neared and superposed at a same face of the board so that a capacitive and/or inductive coupling between the two circuits is realized.

Abstract: A device for measuring a torque applied to a rotating member, comprising: a first rotating member on which a torque to measure is applied; a second rotating member; a free wheel comprising a primary ring and a secondary ring coaxial with and configurable between a coupled movement condition and a free movement condition; sensing means interposed between the first rotating member and the second rotating member and configured to detect an angular phase shift between the two rotating members. During the coupled movement condition, the free wheel is elastically deformable so that the relative position of the secondary ring is angularly shifted with respect to the position of the primary ring with an increase in the torque applied to the first rotating member and the sensing means detect the phase shift for the calculation of the applied torque.

Abstract: A power module or other circuit is formed with transistor assemblies, each having one or more semiconductor slices electrically connected to one another and fixed to a supporting system. The supporting system includes a tubular element suited to allow the flood of a refrigerating and insulating fluid in the inside and which has the semiconductor slices directly welded on its external surface.

Abstract: The invention discloses a power unit (1) which comprises: an accumulator battery (2); an electric converter (3) supplied by said accumulator battery (2); an electric motor (30) supplied by said converter (3); a hydraulic pump (4) mechanically connected to said electric motor (30), suited to put under pressure a liquid (50) which supplies one or more actuators (9) in order to lift a load (11) connected to them. Said pump (4) is of the reversible type and operates as a hydraulic motor suited to drive into rotation said electric motor (30) which operates as a generator supplying said battery (2) by means of said converter (3) whenever the descent by gravity of the load (11) supported by said one or more actuators (9) puts under pressure the oil held therein which passes through said pump (4) entering from the delivery opening (42) and coming out of the inlet opening (41).
