Alstom IGBT VVVF | Class 390 Traction Sound | PWM Inverter - Class 390 Inductor Recording

Class 390 traction inverters - part of the Pendolino platform. This is the 900V Onix 800 programmed with purely asynchronous sinusoidal 2400Hz (±40Hz) PCFM. It's quite clear that this is a very basic FOC algorithm compared to Alstom's other trains that use the Onix 1500 and now Mitrac. Because it's asynchronous-only, it means that the Class 334, 390, 458, 460, and 1995 Stock are all like this since this converter. The only difference is that the Juniper Onix motors have 2 pole pairs (225kW), whereas the Tube train has 4 pole pairs (85kW) and double the peak inverter current rating (95TS@630V/1700Arms Vs Juniper@750V/834Arms). The Pendolino's Onix motors are the most demanding of power, coming in at 425kW which makes full use of the Onix 800 inverter's maximum driving power rating of 490kW.
