自适应IGBT串联均压电路设计
An Adaptive Voltage-sharing Circuit for Serial-connected IGBTs
摘要
Abstract
Abstract： Due to the limits of its voltage withstanding capability, a single insulated gate bipolar transistor （IGBT） cannot meet the need of high-voltage and high-power conversion, such as for energy saving and power quality improvement, voltage source converter based high voltage direct current （VSC-HVDC） transmission, high-voltage frequency converter, static synchronous compensator （STATCOM）, active power filter, and so on. For such applications, serial-connected IGBTs are good choice. This paper proposes an adaptive dynamic voltage-sharing circuit for serial-connected IGBTs and discusses in details. The performance of the circuit is proved through simulations and experiments. Based on the proposed circuit, a full-bridge inverter demonstration system is developed that consists of four sets of five serial-connected IGBTs. Experimental results of the demonstration system show that each IGBT with a rated voltage of 1 200 V works stably at 900 V, while the voltage utilization efficiency is 75 %, indicating the highly practical value of the proposed circuit.关键词
