Abstract

The invention relates to an intelligent high-precision voltage stabilizer with self-adaptive wide dynamic power supply. The main loop of the intelligent high-precision voltage stabilizer comprises one compensation transformer, 4 IGBTs (Insulated Gate Bipolar Translators) and an intelligent driving control system; the four IGBTs under the control of input power live wires and chopped waves are connected with a harmonic suppression inductor L1; a first contact (KM1) head and a second contact (KM2) head are connected with the tail end of a primary side of the compensation transformer (T1); and a third contact (KM3) head is connected in parallel with the first end and the tail end of a secondary side of the compensation transformer (T1). As a voltage value is adjusted and compensated by using a chopped wave control technique, wide dynamic power supply and high-precision voltage output are achieved.

Description

technical field [0001] The invention relates to a voltage stabilizer, in particular to an intelligent high-precision voltage stabilizing device for adaptive wide dynamic power supply. Background technique [0002] For remote areas where the power supply exceeds the power supply radius, it is difficult to guarantee the terminal voltage, the power factor cannot meet the requirements, and the line loss is large; the quality of power supply cannot be satisfied. The voltage stabilizing device is an indispensable component to ensure the quality of power supply; the compensation structure or circuit of the coil type voltage stabilizing device on the market is roughly divided into four types: 1. It is composed of a driving motor, an automatic control circuit and a carbon brush; this type of stabilizing device 2. It is composed of a compensation transformer, a multi-tap voltage regulator and a contactor; this type of voltage stabilization device controls the corresponding taps of the...
