Tips: How does a voltage stabilizer work?
A voltage stabilizer is a device that stabilize the output voltage, it consists of a voltage regulation circuit, control circuit and servo motor. When the input voltage or load changes, the control circuit would sample, compare and amplify the variation, then it drives the servo motor to rotate to change the position of voltage regulator's carbon brush. By automatically controlling the coil's turns ratio, it ensures a stable output voltage.As some electrical appliances contain coil packs, eddy current blocking the current would generate at the initial stage of power supply, the eddy current will weaken the instantaneous voltage when electrical appliances start, and thereof lead to a slow start-up, as well as strengthening the transient voltage generated after open circuit, which may cause sparks to damage circuits. So a voltage stabilizer is needed to protect the normal operation of the circuit.
In this video ATO uses a voltage regulator and multimeter to test the output voltage of the 3 kva voltage stabilizer which has 140V to 270V AC input, 220V AC output. After testing, we may see that the output voltage is within 220V ± 6%, which is in line with the standard.
