Abstract
An energy conversion system for use with an alternative energy source is disclosed. The alternative energy source can generate either an AC or a DC voltage. A first power converter is connected between the source and a DC bus, and a second power converter is connected between the DC bus and the grid or another load. The first power converter is configured to operate during periods of low energy generation. The energy captured will be stored in an electrical storage medium. When sufficient energy is stored, this energy is subsequently transferred to the grid or load via the second power converter. The second power converter is configured to operate intermittently during periods of low power generation, transferring energy from the DC bus when sufficient energy is stored and turning off when the stored energy drops to a point at which the second power converter can no longer be operated efficiently.
