Due to the prodigious proportion of medium and big electronic equipment in power line, the research of three phase reversibleconverter is becoming the researching hotpot on international and native.
USS protocol used for communication between PLC and inverter can compensate for the lack of hardware interface converter and could realize multi-level reversible speed.
