In the just completed , by Deutsche Forschungsgemeinschaft funded project System Analysis and Design of an All-Purpose Synthetical Three-Phase Voltage Source Based on the Modular Multilevel Converter for the Generation of High-Precision and High-Dynamic Voltage Waveforms, a concept for a synthetical 3ph voltage source has been elaborated and a prototype has been built up. Fulfilling the requirements of a synthetical 3ph voltage source, the from Modular Multilevel Converters well-known control concepts have been Extended. The proper function of the 3ph voltage source prototype has been proven by a simulated voltage dip.Further, follow-up funding by DFG is requested in order to investigate the full dynamic performance of the complete control and hardware system. The synthetic 3ph voltage source shall be used in a Power-Hardware-in-the-Loop Emulation System, forming the currents of a simulated converter fed synchronous motor with a pulse frequency of several kHz and a power of 50 kW.

在刚刚完成的由德国研究共同体资助的项目“基于用于产生高精度和高动态电压波形的模块化多电平转换器的通用合成三相电压源的系统分析和设计”中，详细阐述了合成三相电压源的概念，并建立了原型。为了满足合成三相电压源的要求，扩展了模块化多电平变流器的著名控制概念。3ph电压源原型的正确功能已通过模拟电压暂降得到证明。此外，DFG还要求提供后续资金，以研究整个控制和硬件系统的完整动态性能。合成3ph电压源应用于功率硬件在环仿真系统，形成模拟转换器馈电同步电机的电流，脉冲频率为几kHz，功率为50 kW。
