Reducing the impact of traction inverter ripple in electric vehicles

Presented by Haris Muhedinovic, Principal FAE, Vicor

This presentation discusses the challenges posed by ripple currents and voltages generated by the traction inverter in electric vehicles. The ripple can impact other vehicle systems and create problems such as voltage resonance, power losses and audible noise. To mitigate these effects, the use of a high bandwidth DC-DC converter operating above 1MHz is proposed. This allows for a higher cut-off frequency of the input filter, reducing the impact of ripple on the converter and providing a more stable 12V supply. High-frequency DC-DC converter modules are suggested as a viable solution, as they have low switching losses, can tolerate higher ripple voltages, and do not exhibit resonant behavior. Using such converters helps optimize the size, weight, and cost of the converter function by minimizing the need for over-specifying filtering components.
