As the basic component of power conversion device,IGBT（ Insulated Gate Bipolar Transistor） stability and reliability affect the inverter＇s performance directly,so a high requirement for drive circuit should be considered. A design proposal of drive circuit for 500kW photovoltaic inverter was introduced on the base of topological graph and device type,especially studied design principles and some key issues how to drive and protect IG-BT. Lastly,combined with application,the reliability and rationality of drive circuit were analyzed and discussed through the given driving waveforms and inverter current waveforms.
