How does DC power work?
When the mains voltage is converted into the designed voltage by connecting the transformer through the input switch, it enters the pre voltage stabilization circuit. The pre voltage stabilization circuit is used to preliminarily stabilize the desired output voltage, aiming to reduce the voltage drop between the input and output of the high-power regulating tube, reduce the power consumption of the high-power regulating tube, and improve the working efficiency of the DC power supply. The pre voltage stabilization power supply is generally stabilized by switching the output tap of the transformer using a thyristor stepless phase-shifting adjustment relay. After passing through the pre stabilized power supply and filter ①, the voltage obtained is basically stable, and the DC power with relatively small ripple is quickly applied through the high-power adjustment tube controlled by the control circuit to obtain a DC voltage with stable accuracy and performance that meets the standards. Then, after passing through filter ② for filtering, the required output DC power is obtained. In order to obtain the required output voltage or current value, we also need to sample and detect the output voltage and current values and transmit them to the control/protection circuit. The control/protection circuit compares and analyzes the detected output voltage and current values with the values set by the voltage/current setting circuit, and drives the pre stabilized circuit and high-power adjustment tube to enable the DC stabilized power supply to... Output the voltage and current values we have set, At the same time, when the control/protection circuit detects abnormal voltage or current values, it will activate the protection circuit to put the DC power supply into a protective state
