一种具有减小开关尖峰的高升压耦合电感阻抗源逆变器系列

By using coupled inductors, impedance-source inverters can greatly increase their voltage step-up abilities at the expense of high voltage spikes at their dc-links due to leakage inductances. These voltage spikes can then cause damages and greater power losses. Therefore, to better clamp their dc-link voltages, various absorbing circuits have been proposed in this letter for forming a unique famil...
