Shortening simulation time for electronic power circuits e.g. four quadrant DC adjusting circuit

摘要

The determination of switching times and generation of a pulse pattern for energizing semiconductor switches takes place prior to the circuit simulation by an ESPAM program. The conditions for the circuit to be stimulated are two DC sources of 220V, two IGBTs as the power semiconductor switches, flank rise time of energizing signals 0.5E-0.6s, frequency of reference signal (switching frequency) of 10 kHz, rated signal frequency 50Hz, inductive load: R = 20 ohm, L = 20 MH.
