--- 以下为原视频简介 ---
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.

None

Equipment used:
