How Much Do You Know About the Common Sense of Programmable DC Power Supply?

Today, APM Technology will take you to understand the Programmable DC Power Supply. Many people may not understand the DC Power Supply. It is a device that maintains a stable voltage and current in the circuit. For example, dry batteries, batteries, DC generators, etc. all use DC power, so today I will not explain to you a conventional DC Power Supply, but a kind of DC power supply, a programmable DC power supply. Common sense for programming the use of DC Power Supplies.

(1) Application of inductive load
When we turn on or off the programmable DC power supply or change the output voltage, the inductive load will generate an electromotive force in the opposite direction to affect the operation of the programmable DC power supply. In severe cases, it will also cause damage to the programmable DC power supply, so we need to connect a diode in series between the output end of the programmable DC power supply and the load, and connect a resistor and a capacitor in parallel to the load, so as to effectively protect the Program the DC power supply.
(2) Battery load application
When the programmable DC power supply is charging the battery load, we can prevent the power supply from being damaged by connecting the wrong polarity of the battery, so a diode is connected in series between the power supply and the battery, which can protect the programmable DC power supply. Safe use of power.
(3) Pulse load application
Even if the peak value of the current of the pulsed load is within the rated current range of the programmable DC power supply, or the waveform of the pulsed circuit or the motor, within the nominal value indicated by the metering equipment, the current will reach the rated value at this time. current region, which can cause the output voltage to drop or become unstable. The solution is to connect an inductor between the power supply and the load, which can solve the problem very well.
(4) Capacitive load application
Capacitive loads will cause the output voltage to rise, especially when the output voltage is adjusted from high to low, the output voltage will drop very slowly, so a power resistor should be connected in parallel with the output end of the programmable DC power supply. A diode is connected between the loads, which can effectively play a certain role.
The above is APM's explanation of the common sense of programmable DC power supply, I hope it will be helpful to you.
