Dear Darshan, always space phasor modulation is without common mode voltage. Because it's derived from space phasor representation. All other modulation are with common mode voltage. It's normally a problem for electrical machines and will be suppressed. You can develop a new modulation method for your mission!

you can want to know about the generation of common mode voltage in inverter

Dear Darshan, The common mode voltage is the voltage drop between the star point of the machine phases and the DC rail negative plates. There are so many literature available for the reduction of common voltage and it is responsible for the heat generation in the body as the current flows and interact with the resistive part of the body. it is unwanted and affected the performance of the machine e.g. this heat generation may be cause of the failure of the lubrication for the bearings and other moving parts etc.

so many papers are available for this.
