In a system for supplying a variable load at a constant voltage from a variable A.C. source, source variations are compensated by supplying the load over a saturated transformer and load variations are compensated by controlling a saturable inductor on the primary side of the transformer in accordance with the load current. Thus, in Fig. 2, a D.C. load 10, supplied over a rectifier bridge 9 from the saturated transformer 5, is connected in series with the D.C. control windings 11 of the saturable inductor 3 on the primary side of the transformer. Inductor bias windings 14, energized across the load, have a short-circuited portion to provide a path for harmonic current components. A resistor 16 is adjustable with ageing of the rectifiers of bridge 9. In another arrangement, Fig: 1 (not shown), the bias winding is dispensed with. In a third arrangement, Fig. 3, a pair of rectifier bridges 9a, 9b are supplied by separate transformer secondaries for providing D.C. inputs to a switching unit 21 having an output to the load 10, whereby the inputs may be in series or parallel. A composite choke 24 and capacitors 27, 28 provide smoothing for the inputs. Bias winding 14 is energized across one input, and control windings 11a, 11b are separately energized in series with the respective inputs to unit 21. Specification 469,414 is referred to.
