Brushless Mitigation of Bearing Currents in Electric Machines Via Capacitively Coupled Shunting

The overwhelming trend within the industry today is to pair electric machines with variable-frequency drives. It is well known that the use of these drives can introduce high-frequency bearing currents during semiconductor switching events. This paper focuses on bearing discharge currents that gradu...
