The extra money involved in hardware-based common-mode voltage mitigation methods can be overcome by employing modification in the control strategy of inverters. Space vector pulse-width modulation (SVPWM) and modified SPWM are proven to be effective at reducing common-mode voltages in inverters.
PWM-controlled inverters produce substantial common-mode voltage (CMV). CMV causes motor/drive malfunctions and, eventually, system breakdowns. CMV can greatly be reduced by using advanced inverter topologies and modulation techniques. This paper provides a comprehensive review of the many works published on this topic.
In three-phase inverters, modifying the topology by adding a fourth leg is suitable for reducing the common-mode voltage. Utilizing dual bridge inverters is also a reduction method used for common-mode voltage in conventional inverters. These reduction techniques are based on hardware circuitry.
While a two-level inverter converts DC to AC, it generates total harmonic distortion (THD) and common-mode voltage. The common-mode voltage in inverters is harmful to the motor, especially the bearings. Industries relying on large motors employ common-mode voltage reduction methods to prevent their machines from malfunctioning.
