WebMay 9, 2024 · For an accurate calculation, the total loss could be calculated by dividing the IDS and VDS into linear sections, integrating at each section, calculating the power loss per section, and adding them together. On the other hand, I think the basic idea is the same for PFC, but in the case of PFC, the input current is controlled to be sinusoidal ... WebMOSFETs have to be driven just as “hard” during turn-on and turn-off as a bipolar transistor to achieve comparable switching speeds. Theoretically, the switching speeds of the bipolar and MOSFET devices are close to identical, determined by the time required for the charge carriers to travel across the semiconductor region.
