Abstract: 1,119,773. Inverters. BORG-WARNER CORP. 14 Dec., 1965 [11 Feb., 1965], No. 53096/65. Heading H2F. An inverter (one phase of which is shown in Fig. 6) having a pair of semi-conductor switches 22, 23 connected in series with commutating inductances 27, 28 across the D.C. lines 20, 21 has an energy return circuit for the commutating energy stored in each inductor. For inductor 28 this comprises the other inductor 27, diode 50 and a primary winding 48 of transformer 56. Energy is returned to the supply both conductively through this circuit and inductively through the transformer 56 and the rectifying circuit 51, 52 connected to its secondary winding 49. In a more practical circuit (Fig. 7) reverse current diodes 33, 34 are provided which function also as the rectifier connected to the transformer secondary winding. The capacitors 31, 32 are not commutating capacitors but store energy to ensure that when the associated semiconductor switch is turned on energy is rapidly passed to the load. In the embodiment of Fig. 9 the first transformer comprises the windings 62, 63, 64 and the windings of the commutating inductors (all wound on a common core) are extended as shown at 70, 71.

Abstract: An improved electrically actuated solenoid is used to modulate the function of a hydraulic flow control valve. The solenoid operates a control valve to generate a predetermined output pressure as a function of the solenoid input current. An input pressure, provided to the control valve, can thus be modulated to provide a desired maximum controlled output pressure regardless of the input pressure by bleeding excessive pressure to a low pressure return circuit. A lower controlled output pressure is obtained by providing the solenoid with an input current creating a magnetic flux circuit within the solenoid. The magnetic flux circuit displaces an enhanced armature and pole piece configuration which provide a selectable output force dependent on the solenoid input current, regardless of the displacement of the armature relative to the pole piece. By increasing the air gap surface area and increasing the air gap permeability, increases in the output force obtainable from a solenoid of relatively small physical dimensions and relatively low cost is possible. The resulting improved output force versus current characteristics make the use of the solenoid of the present invention possible in a hydraulic control system to increase the portion of pressure bled to the low pressure hydraulic return circuit and thus reduce the controlled output pressure.
