ABSTRACT:
A power distribution system in which the loads are connected in series to a current source. At each load, a current source to voltage source convertor provides alternative current paths. A serial power distribution current path includes a modulated switch (e.g. a pulse width modulated switch) to control the amount of power delivered to the load via a load current path. The load current path includes a diode which couples a capacitor across the switch, providing a semi-regulated voltage input to a d.c. to d.c. convertor connected across the capacitor. The d.c. to d.c. convertor provides a regulated output voltage, which is connected to the load. The control circuit for modulating the opening and closing of the switch is connected in parallel across the capacitor.
