Infineon introduces new 650V CoolMOS CFDA for automotive applications
02 April 2012
Infineon Technologies has expanded its automotive power semiconductor lineup with the new 650V CoolMOS CFDA. The 650V CoolMOS CFDA is particularly designed for resonant topologies such as battery charging, DC/DC converters and HID (High Intensity Discharge) Lighting, also in hybrid and electric vehicles.
This is the first Superjunction MOSFET solution with Integrated Fast Body Diode to meet automotive qualification standard AEC-Q101.
The new generation combines the benefits of fast switching Superjunction MOSFETs such as better light load efficiency, reduced gate charge, lower switching losses, easy implementation and outstanding reliability. The Fast Body Diode is the key for addressing resonant switching topologies used for example, for battery charging and DC/DC converters.
The new 650V CoolMOS CFDA provides lower area specific on-resistance while offering easy control of switching behavior as well as the highest body diode ruggedness in the market. Lower value of Qrr and Qoss at repetitive commutation on body diode reduces switching losses and turn on/off delay times.
Good controllability of rapid current and voltage transients and softer commutation behavior results in reduced EMI (Electromagnetic Interference) appearance, Infineon says. Limited voltage overshoot during hard commutation of the body diode enables easier implementation of layout and design. CoolMOS CFDA provides 650V breakdown voltage, which means an increased safety margin compared to 600V.
Electronics keeps chipping away at EV component costs.
Meanwhile, an ICE 8-speed transmission costs more than a 6-speed.

Basically, ICEVs will cost more and more as their complexity increase. More complex mechanical parts will cost more.
The opposite could be said of BEVs...they will cost less and less as batteries, controls and electrified components will get smaller, lighter and cheaper.
Whenever the cost differential is reduced to almost zero, that will signal the end of ICEVs.

People are saying that the TCO of EVs is already smaller.

What's TCO ?

TCO = total cost of ownership

E-P is correct but the majority does not (yet) buy with TCO in mind.
Electrified vehicle programs should do more to inform potential buyers.
Too many are still buying cars by weight (lbs) thinking that heavier is better. That's how 8000 lbs 4 x 4 were sold.

I thought for a while that the Tango's ballast-plate of lead-acid batteries would help sell it to the "heavier is safer" crowd, but it doesn't appear to be going anywhere.
