Abstract
The present invention relates to a circuit arrangement for mitigating power quality issues. It offers protection to sensitive devices against, for example, voltage sags and swells. The system introduces, for loads connected to an AC power source (e.g. a TV in a home connected to the power grid) a DC power source coupled to a controllable inverter and a controllable switching mechanism. By switching to a series configuration, the DC power source (e.g. a photovoltaic power source) can either draw or supply power in order to mitigate a power quality issue. In normal operation, by switching to a parallel configuration the DC power source can feed the load.
