WebApr 10, 2024 · Turning both MOSFETs off won't do since we can't discharge now. The solution is to rely on the internal body diodes: - To allow discharge, but not charge we turn off the charge MOSFET. In doing so, we still have a current path: through the body diode of the charge MOSFET as shown below.

WebThe MOSFET combines a resistor and a diode, the two previous steps in the evolution of power semiconductors. It also adds a switch that chooses between the resistor and diode modes of operation. When the switch is open, the MOSFET functions as a diode by blocking voltage in one direction and conducting as a diode in the other. WebThe body diode will cause the MOSFET to always conduct in the reverse direction. To switch an AC signal using MOSFET's, you can use two in series, like so. zalaesseo • 9 yr. ago Top comment says yes, but you say no. IMO i've tested myself, and there is indeed a body diode.
