Hybrid systems, as the name implies, combine two or more modes of electricity generation together, usually using renewable technologies such as solar photovoltaic (PV) and wind turbines. Hybrid systems provide a high level of energy security through the mix of generation methods, and often will incorporate a storage system (battery, ) or small fossil fueled generator to ensure maximum supply reliability and security.

[pdf] A common solution is to include a backup power supply in the inverter design that converts HVDC to a low-voltage supply, powering the inverter’s control, sensing and gate drive circuits in the event of a loss of the 12 V input. This power supply is typically a flyback converter.
