(1) Application of Inductive Loads: When opening or closing a programmable DC power supply, or changing the output voltage, an inductive load generates a reverse electromotive force that affects the operation of the programmable DC power supply. In severe cases, it can lead to damage to the programmable DC power supply. Therefore, we should串联 a diode between the output of the programmable DC power supply and the load, and parallel a resistor and a capacitor at the load location. This effectively protects the programmable DC power supply.
(2) In battery load applications, when using programmable DC power supplies to charge battery loads, we can prevent damage to the power supply due to incorrect polarity connection by串联 a diode between the power supply and the battery. This ensures the safe operation of the programmable DC power supply.
(3) Pulse Load Applications: Even when the peak current of pulse loads is within the rated current range of programmable DC power supplies, or the waveform of pulse circuits or motors is within the nominal value indicated by the measuring equipment, the current will reach the rated current area, which may cause a drop or instability in the output voltage. The solution is to connect an inductor between the power supply and the load, which effectively addresses the issue. 36V Aircraft Power Supply, 400Hz Frequency Converter Power Supply, 115/200V Power Supply, 27V DC Power Supply, 400Hz Power Supply, Aircraft Power Supply
(4) Capacitive Load Applications: Capacitive loads can cause an increase in output voltage, particularly when transitioning from a higher to a lower output voltage, where the voltage drop is extremely slow. To address this, a power resistor should be paralleled at the output of a programmable DC power supply, and a diode should be connected between the output and the load. This setup can effectively mitigate the issue.
