The difference between a household automatic voltage stabilizer and a transformer lies in their functions, working principles, and application scenarios. The choice of which device to use depends on specific needs and scenarios. The following is a detailed description by a household automatic voltage stabilizer manufacturer.
Differences in function and principle
Automatic voltage regulator is a device that keeps the output voltage stable by adjusting the input voltage. It controls the working state of the voltage regulator to prevent the output voltage from fluctuating. The voltage regulator plays a role in stabilizing the voltage in the power system to ensure that the load equipment can work properly.
A transformer is a device that transfers electrical energy from one circuit to another, changing the voltage between input and output by changing the ratio of the number of turns of the coil. The transformer provides output voltage according to the input voltage to meet the requirements of the load equipment. It plays an important role in the process of power transmission and distribution.
Differences in operating principle
An automatic voltage regulator(AVR of AC) changes the relationship between input and output voltage by controlling the switching state of the voltage regulator. When the input voltage is lower than the set value, the voltage regulator is turned off and the output voltage is maintained at the set value; when the input voltage is higher than the set value, the voltage regulator is turned on, so the output voltage returns to normal. In this way, the voltage regulator can ensure that the load equipment always obtains a stable voltage when the power system fluctuates.
The working principle of the transformer is based on von Neumann’s law, that is, according to the law of conservation of electrical energy, the input power is equal to the output power. When the input voltage induces a magnetic field through the primary coil, this magnetic field induces a voltage in the secondary coil. Ideally, the secondary voltage is equal to the input voltage multiplied by the ratio of the number of turns of the two coils.
Application scenario differences:
Home automatic voltage regulator is usually used in circuits that require a constant voltage supply, such as electronic devices, to ensure the stability and reliability of the circuit.
Transformers are widely used in power systems, communication equipment, electronic equipment, etc., for voltage conversion, isolation, and distribution.
Summary: Choosing which device to use depends on specific needs and scenarios. A deep understanding of their differences will help us better apply and utilize these two key devices in the power system.
