Multi-State Switching Cell for Single Phase Five-Level Inverter
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 8
Abstract
for low voltage applications, a new T-type inverter topology based on multi-state switching cell is proposed, when medium (or) high switching frequencies are preferred. In this paper the MSSC application presents two topologies of five level inverter. The T-type inverter topology is compared by the Neutral-Point Clamped topology. As the name indicates T-type the conduction takes place in the form of T-shape. In T-type inverter topology the common emitter configurations are used for the switches, it acts like a bidirectional switch; these switches are used to block the half of the dc-link voltage. Due to the reduced blocking voltage, the switch shows very low switching losses. Thus, the THD of output voltage should be reduced. Since the filter ripple frequency is twice the switching frequency, therefore reducing the magnetic weight and size.
