An electrical power recovery apparatus comprises a switching network 6, such as a switch-mode DC to DC converter, a controller 29 arranged to operate the switching network, means to supply DC electrical power to the switching network as a power input, such as a solar panel connected to terminals 25a and 25b, and output lines 10a, 10b, 10c and a return line 11 able to connect the switching network to a load 3. The switching network is operable to provide at least a part of the supplied DC electrical power to the load along the output lines. The switching network is also operable to receive a ripple voltage along the return line and to combine the ripple voltage with the supplied DC electrical power as a power input, thereby harvesting the energy returned in the ripple voltage on the return line. |
