Wide Range Voltage Regulator, What Is The Function Of The Voltage Regulator?

Wide Range Voltage Stabilizer
A switching regulator uses an output stage that repeatedly switches between "on" and "off" states, together with energy storage components (capacitors and inductors) to produce an output voltage. It is regulated by adjusting the switching timing based on feedback samples of the output voltage. In fixed-frequency regulators, the switching timing is adjusted by adjusting the pulse width of the switching voltage, which is called PWM control. In gated oscillators or pulse-mode regulators, the width and frequency of the switching pulses remain constant, but the "on" or "off" of the output switch is controlled by feedback.
Depending on the arrangement of the switches and energy storage components, the output voltage produced can be greater or less than the input voltage, and multiple output voltages can be produced with one regulator. In most cases, pulse (step-down) switching regulators are more efficient than linear regulators in converting power for the same input voltage and output voltage requirements. Compensated---High-precision AC compensated regulated power supplies (single-phase 0.5kVA and above, three-phase 1.5kVA and above) have compensation transformers and have 110V outputs.

Linear Regulators
An LDO is a type of linear regulator. Linear regulators use transistors or FETs operating in their linear region to subtract excess voltage from the applied input voltage to produce a regulated output voltage. The dropout voltage is the minimum difference between the input and output voltages required for the regulator to maintain the output voltage within 100mV of its rated value. Positive output voltage LDO (low dropout) regulators typically use a power transistor (also called a pass device) as a PNP. This transistor allows saturation, so the regulator can have a very low dropout voltage, usually around 200mV, compared to around 2V for traditional linear regulators using NPN composite power transistors. Negative output LDOs use an NPN as its pass device and operate similarly to the PNP device of the positive output LDO.
A newer development uses CMOS power transistors, which are capable of providing the highest dropout voltages. With CMOS, the highest voltage drop across the regulator is caused by the ON resistance of the power device load current. If the load is small, the voltage drop generated by this method is only tens of millivolts.
Voltage stabilizer for laser cutting machine

According to the use requirements of high-power laser cutting machine and the current power supply situation in my country, a voltage stabilizer that meets the requirements of laser cutting machine should be strictly formulated, and an energy-saving product specially developed for stabilizing AC voltage should be developed. When the power supply voltage of the distribution network fluctuates or the load changes, it can automatically ensure the stability of the output voltage. **It has the characteristics of large capacity, high efficiency, wide voltage stabilization range, no additional waveform distortion and phase shift, fast strain time, and stability. It has perfect alarm protection functions such as short circuit and mechanical failure, and the volume should be as compact as possible and easy to use.
