A new seven level boost-type ANPC inverter topology for photovoltaic applications

Abstract Developing of new photovoltaic inverter topologies is received more attention in the last few years. In particular, designing an active neutral-point-clamping inverter type structure is quite popular for PV applications. The output voltage is always half of the input voltage (v in ), which...
