Abstract (en)
[origin: US4878009A] A voltage source with preset values of the source voltage and the internal resistance is simulated by a computing circuit (25, 26; 35, 36; 47) which calculates a reference parameter (SUO; SIO) for a current or voltage regulator (20; 30; 40) that forms the output of the voltage source. The reference parameter (SUO; SIO) corresponds to the output current (IO) or the output voltage (UO) and is obtained from a measured parameter (MUO; MIO) and the input parameters (SU; SR) which correspond to the values to be set. The measured parameter (MUO; MIO) is derived from the output voltage (UO) or the output current (IO). When using this simulation circuit, separate high load resistors and mechanical switching contacts are unnecessary and the input parameters (SU; SR) can be set with analog switches.
