Transformer-less Photovoltaic Inverter
Background: Current inverters for solar power systems are prone to failure and the leading cause of malfunction in solar systems. It is desirable to use transformer-less topologies that are more reliable and longer lasting. Using inverters that do not contain transformers results in higher efficiencies significantly lower size weight cost and complexity. Many transformer-less inverters face the problem of large capacitive ground currents impeding the flow of electrons through the system.
