摘要
Abstract
Voltage-balancing method is the key to the application of series-connected IGBTs. The voltage-balancing process was divided into 4 stages:dynamic turning-on process,dynamic turning-off process,the tail current state and steady state,whose voltage-balancing methods were then proposed respectively:gate compensation capacitor network for dynamic process;RC voltage-balancing circuit designed for tail current state with the capacitance given by a formula;and parallel-connected voltage-balancing resistance for the steady state. Based on the work above, power module of two series-connected IGBTs was designed and tested under high voltage and high current condition. The result shows that under the series total voltage 2 kV(1.85 kV maximum peak voltage for each IGBT)and 2 kA current,the power module balances the voltage of the whole period of and turning on and off process,and both of the voltage-unbalance-rate of dynamic and steady state are less than 5%.关键词
