In the figure we have an interesting protection bridge against power polarity inversion of a circuit using power MOSFETs. MOSFETs must have currents according to the protected load.
The circuit shown was found in the 1994 National Semiconductor's Linear Application Handbook. The...
Phase and amplitude can be controlled in this circuit found in the May 1988 Radio Electronics...
This circuit was obtained from a 1968 documentation and can be adapted to use current equivalent...
