Commutated inverter

WebJul 9, 2024 · In this topic, you study Line commutated inverter – Definition & theory. The line commuted inverter is capable of transferring power from AC to AC or vice versa. The direction of power flow in the inverters is dependent on the triggering delay angle of firming of the SCRs in the inverter. Figure 1.8 shows the block diagram of high voltage ... WebThus, an inverter is a device that converts DC to AC. Self-commutated inverters are classified as current source inverters and voltage source inverters. A voltage source inverter is a device that converts its voltage from DC form to AC form. It can be represented in a single phase or in 3 phases.
