The first part of the DFG project Impedance-Source Inverters for Electrical Power Conversion (PI 595/6-1) was dealing with the magnetically coupled T-Source Inverter. The great advantage of this inverter is a high boost potential at a low shoot-through duty ratio in comparison to impedance-source inverters without coupled inductors like the Z-Source or Quasi-Z-Source Inverter. This high boost ability is achieved by using a transformer with a suitable turns ratio greater than 1. As one can see in theory the inverter has great potential but as it comes to a practical application the coupling of the transformer determines its quality. The stray inductance of the transformer shortens the shoot-through sections, causes overvoltage problems and increases the power dissipation. Because of this quite a few problems had to be solved which delayed the progress of the project. Due to this points it is necessary to apply for a prolongation of the project.

DFG项目“用于电力变换的阻抗源逆变器”（PI 595/6-1）的第一部分涉及磁耦合T源逆变器。与不带耦合电感的阻抗源逆变器（如Z源或准Z源逆变器）相比，该逆变器的最大优点是在低直通占空比下具有高升压电位。这种高升压能力是通过使用具有大于1的合适匝数比的Transformer来实现的。从理论上可以看出，逆变器具有很大的潜力，但在实际应用中，Transformer的耦合决定了其质量。Transformer的杂散电感缩短了直通部分，导致过压问题，并增加了功耗。由于这一点，有相当多的问题需要解决，这延误了项目的进展。由于这一点，有必要申请延长项目。
