For each heatsink model R and have to be defined where Ry is the thermal resistance C W and Cth Ws C models the heat transport delay Cy tdetay Rin The values for and can be calculated using the tool Heatsink from the tools section in Caspoc User defined functions In the Expression block a user defiend function can be defined This block is aimed for simple algebraic equations and is faster than the Cscript block Depending on the number of inputs to the block the inputs areavailable as a b c d Use can be made of Although supported the operator can be used for raising power However it is recommended not to use operator since it is not supported in the ANSI C language To model for example Y Y Output X X use the following equation and define it at the edit field text Text d c b a Text2 File EXPRESSION4 x1 EXPRESSION41 2 a b Y1 EC Y2 Always use enough brackets to structure your equations Store files related to a project To acces various files that belong to one project from the project manager you can simply put them in a directory which has the same name as the main simulation file Both the simulation file csi and thedirectory have to reside in the same directory For example a project ca2. Both variables iVarl and iVar2 are declared for all Cscripts in simulation In this simulation we will use the default value and replace it with a new value In the Cscript the value of iVarl and iVar2 is added and returned as the output of the Cscript block The variables iVarl and iVar2 get a new value being iVarl 3 iVar2 4 and thereby replacing the previous values These new values are set at the outputs of the CVAR blocks The Cscript is shown below int y main y iVarl iVar2 iVarl 3 iVar2 4 return After running the simulation the output of the Cscript block becomes equal to 7 except for the first time step where the output will equal the summation of the default values 1 2 CVAR CVAR CVAR1 CVAR2 3 000 4 000 CSCRIPT a The outputs of the blocks CVAR are equal to 3 and 4 because of the assignment in line 5 and 6 in the Cscript CSCRIPT1 7 000 Heatsink modeling All the dynamic semicondutor models from the library have on the right side a connection for a heatsink model The upper connection represents the losses in the model the lower connection represents the temeprature at the case Select a heatsink model from the library heatsink and connect it to the right side of the semiconductor model More heatsink models can be placed after each other but at the end a block Ambient from the library heatsink has to be placed SCOPE3

6. Getting Started guide we will give a brief resume of the basic operations in Caspoc Both the circuit and the block diagram are drawn in the same schematic So your model contains the electric circuit the control the electrical load or electrical machine plus an eventually mechanical system in one workspace The difference between the electric circuit and the block diagram models is indicated by the appearance of the nodes Electric circuit In the electric circuit you can model your power circuit and calculate voltages over components or between nodes and currents through components The nodes are indicated by round dots One node should be assigned to be the reference ground node which always has a voltage level of 0 volts Caspoc automatically inserts a ground label which you can replace afterwards By clicking the node with the right mouse button a dialog box pops up where you can type the label of the node For a ground reference label type 0 or ground To remove the label press the DEL key Block diagram In the block diagram you can model a dynamic system by using blocks which perform an operation on the inputs of the block For example an ADD block would add the signals at the two inputs and the result is available at the output Block diagram blocks are always operating from the inputs to the output and are automatically sorted by Caspoc The nodes in the block diagram are indicated by square dots Conne
