| Abstract |
A method of determination of power converters steady-state process without calculation of transient process is described. The direct method of solving boundary value problem for system of ordinary differential equations is presented. Piecewise models of semiconductor devices are used, but also other models can be used in this approach. The instants of valve commutations are unknowns of solution vector, which are defined under decision with others unknown variables. Algorithm of Newton is used for obtaining of solution. This method gives decreasing of calculation time when steady-state process are defined. Also the exact values of all unknowns on steady-state period are calculated. This method was checked on simple half-wave rectifier and thyristor resonant inverter in double frequency connexion with back current diodes. Some examples of calculation are presented. |
