Is it possible to switch an AC load using two MOSFETs in anti-series such as the picture below?
In this mode, each MOSFET is on during one half of the wave and the other's body diode conducts to complete the circuit.
With some MOSFET's RDSON approaching 4mOhm, there is very little loss (heat generation) by the FET. However, the body diode or even external Schottkey diode can easily dissipate one watt/ampere given the near 1Volt drop.
Is there a more efficient a circuit that would use just the transistors and no diodes for the typical AC wave?
