A programmable dc power supply is one that allows remote control of its operation through an analog input or digital interfaces such as RS232 or GPIB. Controlled properties may include voltage, current, and in the case of AC output power supplies, frequency. They are used in a wide variety of applications, including automated equipment testing, crystal growth monitoring, semiconductor fabrication, and x-ray generators.
Programmable power supplies typically employ an integral microcomputer to control and monitor power supply operation. Power supplies equipped with a computer interface may use proprietary communication protocols or standard protocols and device control languages such as SCPI.

It is noted that most of the appliances consume electric power in DC. For instance, electric motor, electronics, heating elements, and electric car consumes the electricity in DC. It is also seen that even some 3 phase AC electric motor can’t compete with DC motor in terms of simplicity and efficiency.

Capacitive and inductive parameters don’t limit the capacity of transmission of the DC overhead cable. Also, the conductor cross-section is utilized to its full potential as it doesn’t have any skin effect. This arguably means that it can come handy for long-distance transmission. Hence, it can be quite useful for transmission across large cities, open sea, and the large complex electricity grid.

Implementation of a digital control system can be done to assure instant and accurate control of the active power flow.

Hardware cost that is used in High Voltage DC for the purpose of the long-distance transmission is about 1/3 as compared to its counterparts.

When a DC power line is integrated into an existing AC power grid, then DC power can have achieved fast modulation and perhaps damp the oscillation effect of the AC system. Thus, the stability of the complete system is maintained.

How To Programmable DC Power Supply Work

DC power supplies use AC mains electricity as an energy source. Such power supplies will employ a transformer to convert the input voltage to a higher or lower AC voltage. A rectifier is used to convert the transformer output voltage to a varying DC voltage, which in turn is passed through an electronic filter to convert it to an unregulated DC voltage.
The filter removes most, but not all of the AC voltage variations; the remaining AC voltage is known as ripple. The electric load’s tolerance of ripple dictates the minimum amount of filtering that must be provided by a power supply. In some applications, high ripple is tolerated and therefore no filtering is required. For example, in some battery charging applications, it is possible to implement a mains-powered DC power supply with nothing more than a transformer and a single rectifier diode, with a resistor in series with the output to limit charging current.

What Is The Difference Between Regulated And Unregulated Programmable DC Power Supply

Unregulated DC power supply
Unregulated power supplies are those that are very basic in nature and all they do is lower down the input AC and perhaps change in order to produce DC and just an output cap is added in order to reduce the ripple.In Unregulated supplies, the output voltage is stated by the transformer turns ratio. Hence, the output is directly related to the input AC voltage.
Regulated DC power supply
A lot of modern DC power supply doesn’t work out the way as we have mentioned above. So, any consumer electronics that you would buy these days would have a regulated DC power supply. However, you may still face unregulated supplies from various electronics suppliers.A regulated programmable high voltage dc power supply has the ability to control the output voltage quite actively. Besides this, it has additional circuitry through which the output voltage can be tweaked down and up.

Application Of Programmable DC Power Supply

Programmable DC power supply is used as a testing tool is used in a number of industries, labs, R & D centers, and research institutes. Let us have a brief look at the area of application:-

Accuracy of the programmable dc power supply circuit

Technically, it is defined as the extent to which the result of a calculation, measurement, and specification matches the correct standard of value. Besides this, it also determines the power supply performance by closely matching the theoretical value. In general, the accuracy value are obtained by the quality of the regulation process and the conversion. Both current settings and voltage have accuracy specifications linked with them. The accuracy denotes the point at which the output values matches the international standards.

Resolution of the programmable dc power supply circuit

Resolution is perhaps another factor that you should look out just in case you think of buying a programmable high voltage dc power supply DC electronic power supply. It is perhaps the small change in current or voltage that occurs due to the power supply device. In other words, we can say that resolution is an absolute full-scale percentage or value.

Ripple & Noise of the programmable dc power supply circuit

The programmable high voltage dc power supply output is commonly referred to as random deviation and period. Ripple is commonly defined as the output voltage inherent ac component that is obtained due to internal switching that takes place in the power supply. So, when the signal is viewed in the frequency domain, then the ripples showcase false responses.

Stability of programmable dc power supply circuit

The programmable high voltage dc power supply can get changed if used for the long term. So, in order to maintain the power supply stability, proper calibration and verification need to be done. Hence, for greater stability, the temperature range should be around 20-30 degree.

Transient response of programmable dc power supply circuit

Transient response is denoted as the amount of output voltage deviation due to the change that occurs in loading. So, when the change in the loading takes place, then either the power supply has a lot of stored energy or perhaps not enough of it. Hence, it is not able to react immediately to the new condition. Thus, output capacitors would be responsible for a lack of energy or excess energy.
