yup, or if you have a 2xboost converter between the battery and the inverter then 3*IphasePeak = Iboost, and ~6*IphasePeak=Ibatt. Basically you need an inverter-sized boost converter switch, and it wouldn't surprise me if ultimately you need a motor sized inductor (frequency/size tricks aside). Power in=power out.

It seems a fine strategy for stationary applications, but even your ch-200-nd weighs 50lbs, which is the same as about 3kwh of batteries, plus the boost circuit adds losses. Matching the battery voltage/amperage and motor voltage/amperage is a much better strategy in an ev IMHO.
