Introducing Programmable DC Power Supplies

Release date：2021-11-12

The DC power supply has two electrodes, one is high and the other is low. After connecting the two electrodes, a potential difference will be formed to form the required current. A DC power supply is an energy conversion device that converts other forms of energy into electrical energy.

The electrostatic field generated by the charge alone is not enough to maintain a stable current, so a programmable DC power supply should be used, so that the positive charge can be returned to the positive electrode from the negative electrode with low potential by non-electrostatic action, so as to maintain the potential difference between the two potentials and form a stable current.

The non-electrostatic force of the programmable DC power supply is negative to positive, so when the power supply is connected to the external circuit, the external power supply will form a positive to negative current due to the action of electric field force. Inside the power supply, non-electrostatic forces cause current to flow from the negative pole to the positive pole. This will turn the flow of charge into a closed cycle.

When the internal resistance of the programmable DC power supply is negligible, the electromotive force of the power supply is almost equal to the potential difference or voltage of the two stages of the power supply. If we want to obtain a higher DC voltage, we can use programmable DC power supplies in series. At this time, the electromotive force of the power supply is the total electromotive force of each power supply. However, due to the increase of resistance, only circuits with smaller current can be used. If we want to increase the current, we can use programmable DC power supplies in parallel, so that the resistance will decrease and the current will increase. There are many types of programmable DC power supplies. In different types, non-electrostatic forces are also different, and the nature of energy conversion will be different. Therefore, when choosing a programmable DC power supply, you must purchase it according to your own needs.

Principle and precautions of programmable DC power supply

Programmable DC power supply has two programming methods, one is active, the other is passive. The passive programming algorithm is to change the reaction resistance and the input resistance to change the output value. The active programming algorithm is to change the output value of the reference voltage and the current of the reference. Secondly, there is the programming speed of the power supply.

Rectifier module system: The power rectifier module is the module that converts alternating current into direct current, usually according to the size of the current. It can be used in parallel with multiple modules. The module itself has perfect protection functions, such as input overvoltage protection, output overvoltage protection, output current limiting protection and output short circuit protection.

Waveform characteristics of DC regulated power supply

In the DC voltage regulator circuit, the waveform of the output voltage is mainly manifested in two aspects: ripple and noise. Ripple refers to the periodic fluctuation of the output voltage, which is caused by the AC component of the power supply current. In the circuit, the magnitude of the ripple is related to the capacitance value of the capacitor filter and the load current. The smaller the capacitance value, the greater the load current and the greater the ripple. Noise refers to the output voltage of high-frequency random fluctuations, usually by the components of their own noise and power supply current in the high-frequency components caused. In the DC voltage regulator circuit, the size of the noise is related to the phase noise of the components and the quality of the power supply current.
