Abstract
This paper expresses a circuit simulation of the utility interactive inverter on a photovoltaic system that supplies the utility source with the power generated by solar sells. We realize the inverter circuit works as a complete current type inverter has an immittance conversion link with a high frequency insulation transformer.
Characteristics of this utility interactive inverter are as follows. The inverter output current is in proportion to only PWM output voltage of the high frequency inverter, independent of the amplitude or the waveform of the utility source voltage. The inverter output current to the utility source can be controlled easily, and can be maintained the reference value with very fast response even if the utility voltage changes sharply.
