A voltage stabilizer may be a simple "feedforward" design or may contain a negative feedback control loop. voltage stabilizers may also use electromechanical mechanisms or electronic modules. According to different designs, voltage stabilizers can be divided into DC voltage stabilizers and AC voltage stabilizers. Voltage stabilizers are often used in power supply systems to work with rectifiers, electronic filters, etc., to provide stable output voltages, such as the operating voltages required by microprocessors and other components. In AC generators and even large generators in power plants, the voltage stabilizer controls the stability of the output voltage. In a distributed power distribution system, the voltage stabilizer may be installed in a sub-station or along the direction of the wire extension to ensure that users can obtain a stable voltage regardless of the power level.
