in a customized platform that incorporates a single series of products that are a multi-module
assemblies.
MD series inverter creates three new concepts in the future inverter sector:
1) It creates the three-layer modular structure standard of new generation of inverter. Refer to
Figure 1 for the comparison between traditional inverter and MD series modular inverter;
2) It creates the physical standard for dividing the customer requirements according to such

module as well as various sub-modules. Refer to Figure 2 for the schematic diagram for the
modular structure of MD series inverter;
3) It leads the new industry trend of popularizing the vector control technology.
Such concepts will bring about profound influences on the inverter industry. The modular
structure is described as follows:
