The Design and Simulation of IGBT Inverter Buffer Circuit

Article Preview

Abstract:

In order to suppress the harmonic and protect the IGBT, an innovative buffer circuit for IGBT was designed and simulated in this paper. Compared with traditional buffer circuit, the proposed RCD buffer circuit is more reliable and can reduce the heat effectively when IGBT is turned off. The analytical expression of the buffer circuit is deduced by theoretical calculation. Finally, the performance of the presented buffer circuit was testified by simulation.
