Abstract :
This paper describes the configuration and operation of a novel and efficient interactive inverter composed of 10 kW inverter units arranged in parallel. The efficiency of a proposed 20 kW inverter is 93% at the rated output power and more than 90% at an output power of more than 3 kW when a transformerless inverter is adopted and the number of inverter units in operation is controlled
