Control concept and stability considerations of the Modular High Frequency Converter

Excellent dynamic behavior and controllability even under fault conditions are main requirements of future electric drive systems. The Modular High Frequency Converter (MHF) fulfills these requirements and enables additional advantages especially low weight, low volume and redundant operation after faults. This paper presents control strategies and stability considerations for the new topology of the Modular High Frequency Converter. Simulations and first measurement results of the fully controlled laboratory prototype are shown.
