Solución al Problema 3.
Razonamiento:
La corriente viene impuesta y es dato. Cuando este activado alguno de los transistores y pueda circular atravesándolo lo hará. Cuando el camino se abra a través de algún transistor (o pareja) se polarizará el diodo ( o pareja de diodos) que permita la circulación de la corriente en el sentido en que viene impuesta. La tensión viene impuesta por los interruptores activos.
A . Interv. 0..to . No existe camino a través de los transistores. Se polarizan los diodos D2-D4 y u Carga= -V
Interv. to ..10ms-to Existe camino a través de los transistores T1-T3. u Carga= +V
Interv. 10ms-to.. 10ms . No hay camino a través de transistores. Se polarizan D2-D4 y u Carga= -V
Interv. 10ms .. 10ms+to . No hay camino a través de transistores. Se polarizan D1-D3 y u Carga= +V
Interv. 10ms+to ..20ms-to Existe camino a través de los transistores T2-T4. u Carga= -V
Interv. 20ms-to.. 20ms . No hay camino a través de transistores. Se polarizan D1-D3 y u Carga= -V
B . Interv. 0..to . No existe camino a través del transistor T1. Se polarizan el diodo D4-T3 y u Carga= 0
Interv. to ..10ms-to Existe camino a través de los transistores T1-T3. u Carga= +V
Interv. 10ms-to,10ms . No existe camino a través del transistor T1.Se polarizan el diodo D4-T3 y u Carga= 0
Interv. 10ms .. 10ms+to. No existe camino a través del transistor T2. Se polariza el diodo D3-T4 y u Carga= 0 Interv. 10ms+to ..20ms-to Existe camino a través de los transistores T2-T4. u Carga= -V
Interv. 20ms-to.. 20ms. No existe camino a través del transistor T2. Se polariza el diodo D3-T4 y u Carga= 0
