A novel cascaded H-bridge photovoltaic inverter with flexible arc

Traditional cascaded photovoltaic inverters can be divided into Y-type [1] and delta-type connections [5] with no grounded neutral point; hence, there is no zero-sequence current loop at the 10 kV side. To achieve flexible arc suppression in a PV inverter, the end of it should be connected in Y-type and the neutral point should be grounded.
