The Function Of The Dynamic Voltage Regulator Determines Its Scope Of Application

Dynamic Voltage Regulator (DVR) can be widely used in: electronic computers, precision machine tools, computer tomography (CT), precision instruments, test equipment, elevator lighting, imported equipment and assembly lines in industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, post and telecommunications, hotels, scientific research departments, etc., which require stable power supply voltage. It is also suitable for users at the end of low-voltage distribution networks with low or high power supply voltage and large fluctuations, and for electrical equipment with large load changes. It is especially suitable for all places with high requirements for grid waveforms. Dynamic voltage stabilizers can be connected to thermal power, hydraulic power, and small generators.

Function introduction

Dynamic voltage stabilizer is a power supply circuit or power supply equipment that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of electrical equipment within its set value range, so that various circuits or electrical equipment can work normally under the rated working voltage.

The original dynamic voltage stabilizer relied on the relay to stabilize the voltage. When the grid voltage fluctuates, the automatic correction circuit of the dynamic voltage stabilizer starts to activate the internal relay. The output voltage is forced to remain near the set value. The advantage of this circuit is that the circuit is simple, but the disadvantage is that the voltage regulation accuracy is not high and every time the relay jumps and shifts, the power supply will be interrupted instantly and spark interference will be generated.

This has a great interference on the reading and writing work of computer equipment, which can easily cause error signals in the computer and even damage the hard disk in severe cases.

Most high-quality small voltage stabilizers use the method of motor dragging carbon brushes to stabilize the voltage. This dynamic voltage stabilizer has little interference on electrical equipment and relatively high voltage regulation accuracy.
