Modelica.Electrical.PowerConverters.DCAC.SinglePhase2Level

Single phase DC to AC converter

Information

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.

Modelica.Electrical.PowerConverters.DCAC.MultiPhase2Level

Multi phase DC to AC converter

Information

This is a multi phase two level inverter. The boolean signals fire_p[k] and fire_n[k] for any phase k shall not be true at the same time to avoid DC bus short circuits. The inverter consists of 2*m transistors and two anti parallel free wheeling diodes, respectively, where m is the number of phases.
