What is a cyclo-inverter conversion?
Because of the relatively low power of microinverters, the conversion topology is typically a flyback or perhaps a ‘LLC’ DC-DC stage with maximum power point tracking (MPPT) functionality, followed by a traditional bridge inverter for AC output. A ‘cyclo-inverter’ technique can also be used for single-stage conversion from PV DC to line AC.
