One end of each of the energy sources is connected to an output terminal through a respective diode. The other ends of the energy sources are connected together to another output terminal. The power supply operates so that when the relatively low current is required by a load connected across the output terminals, the high energy density source provides the current; but when the relatively high current is required by the load, the current is provided from the low energy density source. |
