Abstract :
This paper deals with a new transformerless single-phase photovoltaic inverter circuit. The circuit is well suited for thin-film or back-side contacted solar modules because one pole of the solar module can be directly connected to the neutral conductor. The circuit uses a flying capacitor for one of both half-waves, requires only five transistors and is capable of providing inductive as well as capacitive reactive power.
