Hi
i need to integrate the pv with grid, so i used a mathematical modelling of single phase inverter eg input 100v dc i got output as 100v ac(square wave) using triangular pwm technique, i used LCL filter circuit to get sine wave ac output(but iam getting only around 0.2 v ac as sine wave. why the output voltage is too low after filter circuit.
i used LCL(L=2mH, c= 3 microFarad, L=1.3mH)filter.
Please help me ..filter parameter should be designed?please help
