ABSTRACT:
The control for the MOSFET transistors (T1,T2) comprise two low voltage transistors (T4,T3), of which a first transistor (T4) has its base and collector respectively connected to the gate and drain of the direct voltage feed negative side MOSFET transistor (T2) to supply this latter transistor with the initial charge current for its drain, while the base and the emitter of the second low voltage transistor (T3) are connected to the ends of the blocking diode (D4) of the MOSFET transistor (T2) of the same negative side and to the gate of the MOSFET transistor (T1) of the positive side. The MOSFET transistor (T1) of the positive side remains in open condition when the command signal is positive, and shifts to conducting state when the command signal is null.
