Hitachi IGBT VVVF | Class 802 Traction Sound | PWM Inverter - Class 802 Inductor Recording

Class 800/801/802/ traction inverters - the sound of the Hitachi AT300s running on diesel mode! You can hear both the generator converter and the traction converter together, using the same Hitachi IGBT PWM method for driving the motor as with converting power. I believe the synchronous pulse modes are: 3P, W3P, 1P. Take listen and take a look. Noise reduction post-processing: - OC noise floor 44100Hz sample - 48dB reduction - Maximum sensitivity with no smoothing Equipment used: - 1x 1000mH telephone pickup coil to single pole TRS 3.5mm - Sony ICD-PX470 Class 800 Traction Motor Sound Class 801 Traction Motor Sound Class 802 Traction Motor Sound
