• Resumen

  • This paper describes a versatile electrical machine drive simulation procedure. Based on the trapezoidal rule, an arbitrarily configured power electronic circuit is discretized into an equivalent circuit of companion branches, and nodal equations are then set up automatically. The state equations of electrical machines are also solved using the trapezoidal rule. To simplify the procedure and save computing time, the circuit and motor equations are calculated separately and interfaced through Park's transformation. The generalized procedure described in this paper is illustrated by application to the transient performance of an inverter‐fed permanent‐magnet synchronous motor with high pulse‐width‐modulated chopping ratio and ramped reference signal frequency. Computed results are correlated with experimental measurements.
