  • Page 173 Goodrive300-01A series VFD for air compressor Common EMC problems and troubleshooting E.4 Leakage current and residual current device (RCD) As the VFD outputs high frequency PWM voltage to drive the motor, the distributed capacitance against the radiator from internal IGBT and between rotor and stator of the motor may cause the VFD to generate high frequency leakage current against the ground.
  • Page 174 Goodrive300-01A series VFD for air compressor Common EMC problems and troubleshooting in which the first two steps is to measure the resistance of motor stator/rotor while the VFD will output square wave to motor stator winding at 4kHz (default carrier frequency), as leakage current generated by 4kHz carrier frequency against distributed capacitance between motor rotor and stator during charging/discharging is quite obvious, which may cause mal-operation of RCD.
