1. The difference between voltage regulator and transformer
1. Different product meanings
A transformer is a It is an electrical equipment for power conversion, which can convert AC power of one voltage and current into AC power of another voltage and current of the same frequency. Simply put, it converts different AC power into AC power of the same frequency.
A voltage regulator is a power supply circuit or power supply device that can adjust the output voltage. The focus is on adjusting the output voltage.
2. Different working principles
The input range of the voltage regulator slides arbitrarily from 0V to the rated value range, and the input voltage can be adjusted at any time. point to meet the stability of the output voltage. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage according to a certain transformation ratio to achieve voltage conversion.
The working principle of a voltage regulator is the same as that of a transformer. The only difference is that it has a control motor that can adjust the output voltage by changing the coil ratio.
2. The difference between voltage regulator and voltage stabilizer
A voltage regulator is mainly a device used to stabilize voltage output. Almost all voltage regulators use the same process technology to ensure the stability of the output voltage, that is, the input voltage is connected to the error amplifier and the voltage divider resistor is sampled. , the error amplifier forces the voltages at the input end and the output end to remain equal, thereby achieving the purpose of providing a stable current to the load device and ensuring a stable output voltage.
A voltage regulator is a voltage-regulated power supply that can provide adjustable voltage to electrical loads. Its function is to transform an unadjustable power grid. The internal structure of a distribution voltage regulator is similar to that of a line. The winding asynchronous motor, because it often works in a braking state, is similar in principle to the working principle of a transformer. Simply put, the voltage regulator needs to be adjusted manually.
