What is the basic principle of a programmable DC power supply?
There are many types of programmable DC power supplies, and in different types of programmable DC power supplies, the nature of the non-static force is different, and the process of energy conversion is also different. In chemical batteries (e.g., dry cells, storage batteries, etc.), non-static electric force is associated with the dissolution of ions and the deposition process of chemical action, chemical batteries discharge, chemical energy is converted to electrical energy and Joule heat in the temperature difference power supply (e.g., metal temperature difference couples, semiconductor temperature difference couples), non-static electric force is associated with the diffusion of temperature differences and the concentration of electrons difference, the temperature difference power supply to the external circuit to provide power, thermal energy is partially converted into electrical energy. In a DC generator, the non-static force is electromagnetic induction, and mechanical energy is converted into electrical energy and Joule heat when the DC generator supplies power. In a photovoltaic cell, the non-static force is the photovoltaic effect, photovoltaic cell power supply, light energy is converted into electrical energy and Joule heat.
In production testing, the wide range voltage output of a programmable DC power supply is suitable for testing and analysing the characteristics of components, circuits, modules and complete devices. So what are the basic principles of a programmable DC power supply?
The non-static force in a programmable DC power supply is directed from negative to positive. When a programmable DC power supply is connected to an external circuit, on the outside of the power supply (external circuit), a current is formed from the positive pole to the negative pole due to the electric field force. Inside the power supply (internal circuit), the non-static electric force causes the current to flow from the negative pole to the positive pole, so that the flow of charge forms a closed loop.
Programmable DC power supply with built-in automotive electronic engine start test waveforms in accordance with the German DIN40839 standard and voltage interruption test waveforms in accordance with the international ISO16750-2 standard provides solutions for the automotive electronics industry. It eliminates the cumbersome editing process before testing. Meanwhile, test engineers can adjust the setting parameters of the waveforms by themselves in order to output waveforms under different test levels.
