voltage regulator with capacitor: static voltage regulator

The working principle of static voltage regulator:

Static voltage regulators are designed to help create reliable and predictable capabilities, while also reducing the risk that electrical systems can cause harm.


Electricity Regulation

The power system is "regulated" when the electrostatic voltage regulator very quickly creates a constant voltage fluctuation, based on the limited capacity of electricity. This control is achieved through the use of a gas-filled regulator tube, which can be based on the Virtual Academy of Applied Science.

 

Coil transmission

The static voltage regulator is designed to have a wide input voltage range and reliable output voltage for stable use of changing coil systems, which can be limited according to the power supply's capacity. The equipment connected to the regulator has its electricity transferred to the autotransformer, which changes the coil and prevents sudden fluctuations in voltage, thereby making the electrical system safer.

effectiveness

Static voltage regulators are designed to not place a lot of burden on the electrical system, and part of them is limited according to the power capacity(Static Mobile Power Inverter: Static Mobile Power Inverter of offices). They operate very fast because they have thyristors and the increased response speed is in the voltage charge.

 

The inductance and capacitance of the voltage regulators do not send very used electricity back and forth to each other, so these regulators place a very little burden on local regulators, according to the Virtual Academy of Applied Science.

 

control

The static voltage regulator is controlled by a microprocessor, which is a very small computer processing system. These microprocessors not only allow the supervisor to be controlled but also record the operation of the electrostatic voltage regulator, based on limited power capabilities.

 

Static voltage regulators usually function automatically, although they are usually designed to allow the owner of the regulatory agency to take manual control functions. Remote monitoring is possible through serial ports and dry contact ports. These regulatory agencies should also have a manual bypass switch.

 

high temperature

Static voltage regulators are designed to operate at very high temperatures, depending on the limited power capacity. Electrical systems are used in various environments and use large amounts of electricity to generate large amounts of heat, thereby increasing the probability of electrical fluctuations in industrial situations.

 

Safety

Although the purpose of the static voltage regulator is to make the power system safer, safety precautions must be observed when using the voltage regulator. When it is wet, the voltage regulator according to the notification UPS should not operate. This machine must also be connected to the ground so that it can spread the charge to the ground.

Considering the complexity of modern switching voltage converter modules, the choice of filters and tank circuits for input and output capacitor chips seems to be a trivial part of power supply design. However, it is not. Incorrect selection of technology, size, capacitance, or ESR can show that low capacitance will destroy the efficiency of the circuit at best, and at worst will lead to premature failure of the product. The suggested method is to calculate the initial capacitance and ESR value using the extensive information provided in the supplier's datasheet, and then test the prototype circuit using several alternative devices in a variety of technologies.

In the LC output filter, the function of the capacitor is to maintain a constant output voltage (VOUT) and limit any voltage spikes. In fact, it is practically impossible to eliminate the voltage change near the target value, which manifests as an oscillation between the maximum and minimum values, and the difference (ΔVOUT) is called the peak-to-peak voltage ripple. Voltage ripple is a function of inductor ripple current, switching frequency, and output capacitor ESR.


Modular DC-DC switching voltage converters (or regulators) are fully integrated devices that can eliminate most of the complexity of power supply design-but not all.
