Circuit calculation is common in magnetic field transient analysis or integration analysis. JMAG provides not only basic components but also pre-installed macro components that aggregate functions. In addition to electrical circuit components, there are also control system components. This script places the pre-installed PWM 120deg conduction system (3-phase) component and sets its parameters.
Preconditions
- One or more magnetic field transient analysis or integration analysis studies must be created.
This script runs for the active study in the project tree.
Script Function
- To set up a circuit, it must be created first. Check whether it has already been created, and if not, create it.
- Create and place the PWM 120deg conduction system (3-phase) macro component.
- The PWM 120deg conduction system (3-phase) component parameters are 4 poles and 1,000 Hz carrier frequency.
