PURPOSE:To keep a voltage across an autotransformer constant, by connecting the primary winding of a transformer having the secondary winding and an autotransformer in series for input terminals and adjusting the impedance of the secondary winding. CONSTITUTION:The primary winding L1 of a transformer T1 having the secondary winding and an autotransformer T2 are connected in series and a voltage V-V+V' with fluctuation is applied between terminals A and B. A variable impedance P is connected to the secondary winding L2 of the transformer T1, a sliding pint (b) can be adjustable from a point (a) to a point (c), and the (b) is slided to compensate a voltage V' depending on the amplitude of the fluctuation component V' of the power supply voltage. A load Z is connected to output terminals C, D of the autotransformer T2. Thus, the load Z can always have a constant voltage V. This system is suitable for a permanent magnet type generator of two-pole construction. |
