This is the simplest power MOSFET drive circuit.
The resistor R
reduces turn-off time.
R
built-in resistor.
(T
Both AC and DC drivers become possible by
connecting power MOSFETs in a common-source
configuration.
Photovoltaic couplers in a parallel-serial
configuration convert AC power to DC without a
transformer.
This type of configuration requires tens to hundreds
of photovoltaic couplers.
