How to distinguish between regulators and voltage regulators

Voltage regulator: regulator is divided into oil-immersed regulator, autotransfer regulator, isolation regulator, induction regulator, column electric regulator and thyristor regulator five.　Regulators work in manual voltage regulator and electric voltage regulator. Thyristor regulator also known as "thyristor power regulator" "silicon controlled power regulator" or simply "power regulator". "Thyristor" also known as "silicon controlled" (SCR) is a four-layer three-terminal semiconductor devices, it is connected to the power supply and load in the middle, with the corresponding trigger control circuit board, you can adjust the voltage, current and power added to the load.　"Thyristor regulator" is mainly used for heating power adjustment of various electric heating devices (such as electric industrial kiln, electric dryer, electric oil furnace, various reaction tanks, reactors, electric heating devices), which can be adjusted manually, but also can be adjusted with electric regulating instruments, intelligent regulating instruments, PLCs, etc. Instrumentation, intelligent regulating instrumentation, PLC and computer control systems, to achieve a constant value or program control of the heating temperature. Voltage regulator: as the name suggests, is to make the output voltage stabilization equipment. All voltage regulators, all use the same technology to achieve output voltage stabilization output voltage by connecting to the error amplifier (Error Amplifier) inverting input (Inverting Input) voltage divider resistor (Resistive Divider) sampling (Sampled), error amplifier in-phase input (Non-inverting Input) is connected to the error amplifier in the same phase (Non-inverting Input) to achieve the output voltage stabilization. The inverting input of the error amplifier is connected to a reference voltage Vref. The reference voltage is generated by the IC's internal bandgap reference. The error amplifier always tries to force its two inputs to be equal. For this purpose, it provides load current to ensure that the output voltage is stabilized. Voltage regulator: it is a kind of power supply circuit or power supply equipment that can automatically adjust the output voltage, and its role is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of the electrical equipment in its set value range, so that all kinds of circuits or electrical equipment can work normally under the rated operating voltage.　Voltage regulator: large tens to thousands of watts of AC voltage regulator, is the supply of large-scale experiments and industrial, medical equipment, the work of the power supply. There are also small a few watts to a few kilowatts of AC voltage regulator, is for small laboratory or home appliances to provide high-quality power supply, the initial power regulator is to rely on the jump of the relay to stabilize the voltage. When the grid voltage fluctuates, the power regulator's auto-correct circuitry kicks in, causing the internal relays to operate. Forcing the output voltage to remain near the set value, the advantage of this circuit is a simple circuit, the disadvantage is that the accuracy of voltage stabilization is not high and every time the relay jumps to shift, it will make the power supply a transient interruptions and sparks interference.　This is a great deal of interference to the computer equipment reading and writing work, easy to cause computer error signals, and in serious cases will also make the hard disk damage.　Now high-quality small voltage regulator, most of the motor drag brush method of stabilizing the voltage, this regulator on the electrical equipment produced by the interference is very small voltage regulator accuracy is relatively high.
