Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This is a single-phase two level inverter. The boolean signals fire_p and fire_n shall not be true at the same time to avoid DC bus short circuits. The inverter consists of two transistors and two anti parallel free wheeling diodes.
An example of a single-phase inverter with PWM voltage control is included in Examples.DCAC.SinglePhaseTwoLevel.
