Title:
ALTERNATING-CURRENT VOLTAGE STABILIZER AND ALTERNATING-CURRENT VOLTAGE STABILIZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/196629
Kind Code:
A1
Abstract:
The present invention is adapted to the technical field of voltage stabilization. Provided are an alternating-current voltage stabilizer (1) and an alternating-current voltage stabilizing device. The alternating-current voltage stabilizer (1) comprises: a tap gating circuit (12) and a multi-tap mutual inductance transformer (11); multiple taps of the multi-tap mutual inductance transformer (11) are provided on a primary winding thereof; a secondary winding of the multi-tap mutual inductance transformer (11) has one end used for connecting to a live wire end of an alternating-current input and the other end used for connecting to a load; the other end of the secondary winding is further connected to a neutral line end of the alternating-current input by means of the tap gating circuit (12). The tap gating circuit (12) comprises multiple controllable switch branches connected in parallel, and the number of the controllable switch branches is consistent with that of the taps of the primary winding; each controllable switch branch comprises two controllable switches connected in series, and each tap of the primary winding is connected between two controllable switches of the corresponding controllable switch branch. The cost of the alternating-current voltage stabilizer (1) can be reduced.
