In order to obtain a higher DC voltage, high-power programmable DC power supplies often use DC power supplies in series. At this point, the total potential is the sum of the potentials of each power supply, and the total internal resistance is also the sum of the resistances of each power supply. Due to the increase in internal resistance, high power programmable DC power supplies can usually only be used in circuits where the required current intensity is small. In order to obtain a higher current intensity, DC power supplies of equal potential can be used in parallel. At this point, the total potential is that of a single power supply, and the total internal resistance is the parallel value of the resistance of each power supply.
