Thanks for that info. Makes sense. So, the FETs work harder because of the higher partial currents, but does the coil or diode (assuming it's not running into saturation) work any harder?
Yes, both do -- the diode recirculates longer, and the peak currents are higher in the coil. Capacitor currents are higher too, but they don't even get slightly warm...
