Typical power circuit configuration involves 3 phase diode
rectifier at the input to convert the AC input to DC
voltage, LC or C filter to reduce the ripple in the DC
voltage. 3 phase IGBT inverter stage converts this DC
voltage into variable voltage variable frequency output as
per the desired pattern.

prove that inegration of { e^z / z^2 + pi^2 }dz is equal to i/pi by Cauchy Residue Theorem.
