第六讲ＩＰＭ模块与变频器的可靠性变频器的核心主体是功率器件 ,变频器从诞生到目前的水平 ,其每一重要更新都体现在功率器件的更新上。这里不再提及早期的可控硅器件。从 80年代大功率晶体管 (ＧＴＲ)器件出现 ,电压型变频器开始得到推广应用。 80年代末出现了新的功率器件—
Chapter VI Reliability of IPM Module and Inverter The core of inverter is the power device. From the birth to the current level, the inverter is reflected in every update of power devices. No mention of earlier thyristors. From the 80’s high-power transistor (GTR) devices appear, voltage-frequency inverter began to be widely used. The late 80s appeared new power devices -
