Dynamic and Steady State Response Analysis of Selective Harmonic Elimination in High Power Inverters

Selective harmonic elimination (SHE) technique has drawn tremendous interests for its superior harmonic performance, especially in high power devices where switching power loss and passive filter size are the main concerns. However, the drawbacks of slow dynamic response and difficulties in hardware implementation limit its engineering application. Based on a 3-level inverter, this paper analyzes the dynamic response of SHE. A system model is...
