| Abstract |
This paper investigates performance differences of fixed and variable time–step network
simulation methods by comparing accuracy and execution time of five commercial packages. A set of
benchmark cases covering multiple three-phase diode rectifiers and a PWM voltage source inverter
show that fixed time–step methods are superior in terms of execution time for line-commutated
circuits. However, even low switching frequency PWM applications may require very small time
steps in order to lead to accurate results. It is concluded that PWM inverter control signals may be
significantly in error even when wave forms appear correct when too large a time step is used. |
