Common wiring methods for DC power supply systems
There are three main wiring methods for DC power supply systems:
1. Single connection method: Connect the load directly to the output port of the DC power supply system. This method is suitable for situations where a single load is connected.
2. Multi way parallel connection method: Connect multiple loads in parallel at the output port, where each load can take the same voltage and current. This method is generally used in power supply situations.
3. Multi channel series connection method: Multiple loads are connected in series at the output port, with each load taking a different voltage and current. This method is generally used in testing scenarios to obtain data for different voltage and current combinations.
In short, DC power systems play a crucial role in today's society. It is precisely because of the important role and wide application of DC power supply systems in power supply, charging, testing and other fields that various emerging electronic devices, intelligent hardware, etc. have rapidly developed and grown, bringing people a more convenient and efficient living experience.
Precautions for measuring ripple in DC power supply
Measurement environment
The measurement environment should be stable to avoid environmental factors such as temperature and humidity affecting the measurement results.
Calibration of measuring instruments
Measuring instruments should be calibrated regularly to ensure the accuracy of measurement results.
Grounding of measuring instruments
The grounding of measuring instruments should be good to avoid poor grounding affecting the measurement results.
Input impedance of measuring instruments
The input impedance of the measuring instrument should be large enough to avoid affecting the tested circuit.
Time
The measurement time should be long enough to ensure the stability and reliability of the measurement results.
Selection of measurement methods
Select appropriate measurement methods based on the parameters and requirements of the tested power supply, such as oscilloscopes, AC millivoltmeters, etc.
