Edc=240; // in V (battery voltage)
M=0.8; // modulation index
// calculate
E0_rms=Edc; // calculation of rms output voltage
E0_fund=M*Edc/sqrt(2); // calculation of Fundamental output voltage
DF=M/sqrt(2); // calculation of distortion factor
HF=sqrt(2/M^2-1); // calculation of harmonic factor
G=M/sqrt(2); // calculation of gain of the invertor
