Property name="VALUE" value="example file: simplis_002_constant_power_load.sxsch\n\nThis example models a constant power load such as the DC/DC converter input characteristics\nwhen operated from the output of a PFC converter. The load characteristics are defined as a\ntable of PWL points. These points were calculated in the file simplis_002_constant_power_load.xls, \nthen copied from the spreadsheet and pasted into the dialog for R1 using the \"Paste\" button.\n\nBelow the DC/DC converter turn-on voltage of 195V, the load has a resistance of 1Meg ohm.\nAbove the turn-on threshold, the load enters constant power operation at 200W. Above 420V, the load\nagain becomes resistive and has a resistance of 400 ohms. The first and last PWL segments must\nhave positive resistance or a syntax error will be generated. Usually these segments can be placed\noutside the region of normal circuit operation, where the positive resitance slopes will have no effect.\n\nDuring steady-state operation, where the voltage is between 355 and 410V, the constant power load \nwill operate on a single segment. Operating on a single segment while in steady-state will maximize \nsimulation speed, as the load is represented by a single, constant, resistance.\n" autopos=0 x=0 y=156 align=LeftBase linear=1 selectable=1 font=FreeText Netnames .EndInstance Wire x1=3960 y1=3120 x2=3600 y2=3120 net="3" branch="-:V1#P" Wire x1=4200 y1=3120 x2=4560 y2=3120 net="#VOUT" branch="+:R1#P" Wire x1=3600 y1=4560 x2=3960 y2=4560 net="0" branch="-:V1#N" Wire x1=4560 y1=3720 x2=4560 y2=3120 net="#VOUT" branch="+:R1#P" Wire x1=3600 y1=3600 x2=3600 y2=3120 net="3" branch="+:V1#P" Wire x1=3960 y1=4560 x2=4560 y2=4560 net="0" branch="+:R1#N" Wire x1=4560 y1=4080 x2=4560 y2=4560 net="0" branch="-:R1#N" Wire x1=3600 y1=4080 x2=3600 y2=4560 net="0" branch="-:V1#N" Text value=".SIMULATOR SIMPLIS\n.PRINT\n+ ALL\n.OPTIONS\n+ PSP_NPT=5001\n.TRAN 500 0\n\n.GRAPH \"xy(IPROBE1#P, :#VOUT )\" axisType=\"auto\" persistence=-1 curveLabel=\"Load Current\" xLog=\"auto\" yLog=\"lin\" xLabel=\"Load Voltage\" xmin=0 xmax=500\n\n.GRAPH \"xy( :#VOUT*IPROBE1#P , :#VOUT )\" axisType=\"grid\" persistence=-1 curveLabel=\"Power\" xLog=\"auto\" yLog=\"lin\" \n\n.SIMULATOR DEFAULT\n" SimulatorMode value="Simplis" LicenseInfo version="7.20j" product="SIMetrix/SIMPLIS" Property name="NetName" value="" type=value Property name="UserVersion" value="15" type=value .EndSchematic .EndComponent
