Abstract
A switching circuit, typically a thyristor bridge, is connected to a source of waste energy. The source can be waste energy occurring as a by-product of man's activities such as waste heat energy, stored water, or the potential mechanical energy of elevated objects. The source provides d.c. power either directly or through conversion. The switching circuit is also connected to an a.c. load and across a.c. power mains energizing the load. The switching circuit is operable to periodically connect the waste energy source to the a.c. load in a power supplying manner. The a.c. mains impart suitable voltage and frequency characteristics to the electrical power so supplied. In the event the supplied power exceeds the power required by the a.c. load, the difference is taken by the a.c. power mains.
