Abstract
The utility model relates to a superposed AC voltage regulator, which comprises a control part, voltage-regulating control switches and voltage-regulating transformers TB1, TB2, TB3, wherein the voltage-regulating control switches are contactors K1, K2, K3, K4, K5, K6; the voltage-regulating transformers TB1, TB2, TB3 are single-phase primary-side tapped voltage-regulating transformers; the control part, the contactors K1, K2, K3, K4, K5, K6 and the voltage-regulating transformers TB1, TB2, TB3 form electric connection one by one. Two ways of voltage of the superposed AC voltage regulator in a circuit, which participate in superimposition, are divided into main voltage and regulating voltage; the main voltage directly comes from network voltage; the regulating voltage is generated by one voltage-regulating transformer; the primary side of the voltage-regulating transformer is directly connected to the main voltage. Thus, the secondary side of the voltage-regulating transformer can obtain AC voltage which has the same frequency and the same phase with the main voltage or has the same frequency and opposite phase with the main voltage; then the secondary side of the voltage-regulating transformer is superimposed with the main voltage to generate output voltage. When output voltage of the voltage-regulating transformer alters, the output voltage after superposed also alters.
