Siemens IGBT VVVF | Class 380 Traction Sound | PWM Inverter - Class 380 Inductor Recording

Periodic Carrier Frequency Modulation (PCFM) is back and bold! The Class 380 is the only Desiro UK whose car takes on a different form. The profile is a stark contrast from the other trains which came before it. It uses newer materials and systems that make it rather unique. Pulse modes: 675Hz (+/- 50Hz) PCFM, 1000Hz (+/- 50Hz) PCFM all the way up to 100Hz fundamentally, W3P 00:00:00 Electromagnetic 00:55:09 Natural Sound 01:50:17 Electromagnetic & Natural Sound Noise gate post-processing: Notch filtered auxiliary noise Equipment used: 2x 1000mH telephone pickup coil Tascam DR40X Class 350 Traction Motor Sound Class 360 Traction Motor Sound Class 380 Traction Motor Sound #induction #train #inductorwindingmachine #motor #vvvf #vvvfインバータ #vvvfサウンド
