| Abstract |
This paper presents basic ideas for programmable Modules (components) used in simulation of power electronic circuits. Such a function is frequently questioned by experienced designers who are not satislied by the standard components available, and should be an inevitable part of any general purpose program (like SPICE and EMTP). Programmable Modules can be used to simulate nonlinear dynamic problems described by algebraic, differential or logical equations. Examples of applications are detailed models of switches, electrical machines (advanced two axis modelling), controllers for resonant converters (including sampled systems) and average models tor high frequency switching. After the Modules are programmed they are appliable as ordinary circuit components connected arbitrarily in the circuit. Many Modules can be used simultaneously with individual parameters. The paper focus on the need for such Modules, mathematical description of Modules in connection with the global circuit, and the solution of the differential and algebraic equations. |
