Abstract

The authors describe the development of the basics for the determination of the maximum obtainable switching frequencies of a 20 kW, 820 V/50 V full-bridge DC-DC converter designed with (second-generation) 1200 V/50 A IGBTs (insulated-gate bipolar transistors). Because the turn-on losses can be almost completely avoided by phase-shift PWM (pulse-width modulation), emphasis is placed on the determination of the turn-off losses. The dependencies of the switching power losses per switching cycle on the load condition and on the junction temperature are investigated for the following cases: simple PWM (switching without snubber), switching with capacitive parallel branch (turn-off snubber network), and force commutation of the power electronic switches using a commutation circuit (zero-current switching). The results obtained indicate the possibility of rating the overall effort linked to a given operating mode of the power electronic devices. The limits of the operating region of the converter system can also be determined.<>

1200v / 50a零电压或零电流开关IGBT的关断行为和开关损耗分析

作者描述了用(第二代)1200 V/50 a igbt(绝缘栅双极晶体管)设计的20 kW, 820 V/50 V全桥DC-DC转换器的最大可获得开关频率的基本原理的发展。由于相移PWM(脉宽调制)几乎可以完全避免导通损耗，因此重点放在关断损耗的确定上。研究了简单PWM(无缓冲器开关)、容性并联支路开关(关断缓冲器网络)和使用整流电路强制整流的电力电子开关(零电流开关)三种情况下，每个开关周期的开关功率损耗与负载条件和结温的关系。所获得的结果表明，评定与电力电子设备的给定工作模式有关的总努力的可能性。还可以确定变流器系统工作区域的极限。
