I agree. I read the paper and I do not see anything new except a single chip solution. Also, I looked at their software library description and I see the standard routines for vector motor control.

Even my daily driver 1994 US Electricar has a combination of a control processor and a DSP to generate the high speed PWM signals for the motor inverter, charger and DC/DC. Granted, that old design uses 2 separate chips to achieve what this company proposes in a single processor, but I do not see how this can be considered revolutionary in the car industry or how it can achieve up to 30% efficiency improvement. The whitepaper does not show it. So, until I get *data* that shows otherwise, I still consider this company in a PR effort to get new funding/customers and to do that, they make claims that seem to stretch the truth....

Their claim is based on a white paper that is available on their website.
