Multilevel Converter

Research Background

As the high-speed develop of technology and rapidly expand of industrial produce scale,therewith the requirement of energy is increasing continuously.Traditional two-level converter cannot match high voltage,high power demands.Hence more and more researchers make deep research and application of multi-level converters gradually.Multi-level converters is a hotpot of grid technology application which provide a new method to achieve high power,high efficiency,high voltage and high power quality transmission.But multi-level converters always along with complex structure,high voltage,it’s inefficiency,expensive and dangerous to test with physical hardware platform.Therefore by using HIL Real-Time simulation,achieves a efficient ,convenient,safety and accuracy test.And this test method becomes a  major certify test form.

Starsim HIL Simulation Solution
