What is Dynamic Boost and how does it works?

Dec , 03 2021

As with the current‐controlled automatic boost system, Dynamic Boost includes no pre‐programmed boost timer. Unlike the current‐controlled automatic boost system, however, Dynamic Boost automatically adjusts boost duration to take into account differing parasitic DC loads and other variables discussed above. The principle behind Dynamic Boost is simple and straightforward. Refer back to Figure 1. ...

Power Regulation Solution

Mar , 28 2022

Due to the influence of various factors such as power supply facilities and regional conditions, the voltage fluctuation of the AC power supply grid in some countries is still relatively large. Specially in some remote and rural areas of countries with unstable urban networks. The main conditions of AC power grid voltage fluctuation are as follows: (1) The voltage fluctuates high and low, and cann...

How a Voltage Regulator Works

Aug , 22 2022

All voltage regulators utilize the same technology to stabilize the output voltage. The output voltage is sampled (Sampled) through a resistor divider (Resistive Divider) connected to the inverting input terminal (Inverting Input) of the error amplifier (Error Amplifier), and the non-inverting input terminal (Non-inverting Input) of the error amplifier is connected to a reference voltage Vref. The...

What are the installation steps for the voltage stabilizer?

Aug , 22 2022

The voltage stabilizer is composed of voltage stabilizer and constant voltage, control circuit, and servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison and amplification, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and the coil turns ratio is automatically adjusted to mainta...

The working principle and control method of IGBT voltage modification method

Nov , 03 2023

Unlike the resistance method, the voltage method involves changing the driving voltage during the control phase to control voltage and current overshoot. There are approximately two methods to change the driving voltage. One is to achieve the change by dividing the driving voltage through a resistor, and the other is to change the output signal in the control chip (DSPFPGA), and then convert it in...

Principle of overvoltage and undervoltage

Jan , 13 2024

The overvoltage and undervoltage protector is installed in the distribution box. Its main function is to cut off the power supply in a timely manner when the low-voltage distribution line or electrical equipment malfunctions, causing an increase or decrease in the voltage of the distribution system, thereby avoiding losses to components or distribution systems. This article mainly introduces the w...
