Abstract

The invention discloses a low-voltage wide-range input AC voltage stabilizer. The number of turns of the coil of an outer-layer coil winding is designed to be greater than that of turns of the coil ofan inner-layer coil winding, so the stable-voltage output can still be guaranteed when the input voltage is low, the lowest input voltage can reach 90 V or even 50 V, the lower limit of the input voltage is greatly widened, the bottleneck that the lowest input voltage of a common voltage stabilizer is 160 V is broken, and the low-voltage stabilizing function is achieved; meanwhile, a switching tap is additionally arranged on the outer-layer coil winding, so the upper limit of the input voltage can be increased; for example, the upper limit of the input voltage can be increased to 300V from 250V, and the stability of the output voltage during voltage reduction output is ensured; a shutdown reset circuit is used for enabling a carbon brush assembly to stay on the coil, close to the farthestend, of the outer-layer coil winding after shutdown, so it is guaranteed that the input resistance of the voltage stabilizer is the maximum value during startup, the startup inrush current can be reduced, and the impact on the voltage stabilizer during startup is reduced.

Description

technical field [0001] The invention belongs to the technical field of AC voltage stabilizers, and in particular relates to an AC voltage stabilizer with low-voltage wide-range input and a use method. Background technique [0002] The automatic AC voltage stabilizer consists of a specially designed voltage regulator or transformer and a controller or control circuit to form a closed-loop control system.
