3 Typical Application Scenarios for Traction Inverters

There are many ways to design traction inverters but most share the similar ADC sample and PWM update scheme. This section provides two typical design examples for traction inverters operated in up-down counting or center-lined timing PWM. The cases are listed below. Unless new frequencies are specified in the following sections, the cases are analyzed in the condition of both PWM and resolver sinusoidal excitation frequency at 10 kHz.

  • Sample ADC in cycle 0 and update PWM in cycle 1
  • Sample ADC in first half of cycle 0 and update PWM in second half of cycle 0
