چکیده

abstract


In recent years, a numerous Multi-Level Inverter (MLI) topologies are proposed with reduced number of switches and control complexity. An Impedance source based MLI structure with ability of additional boost is proposed in this work. The proposed topology requires one source, one impedance network and reduced number of switches when compared to recently reported inverter literature. Due to Selfvoltage Balancing circuit (SBC), the fixed boost of 1.5 times the input and equal voltage across all the capacitors are achieved. An additional boost is obtained by placing impedance network between input source and SBC. The proposed Inverter is compared with existing topologies with respect to a number of sources, number of impedance networks, control switches, voltage balancing and boost capability. A simple level shifted based sinusoidal pulse width modulation technique is adopted for generating gate pulses. Further theoretical analysis and computer aided simulation results are validated with the experimental results.

Conclusions


This paper proposes Impedance Source Switched Capacitor Multilevel Inverter with enhanced boost capability with less number of switching devices compared to conventional and recently reported multilevel inverters. Seven level output is achieved by using one input source and one impedance network. The balanced voltage across all the capacitors is obtained by using self-voltage balance circuit. All the capacitors are charged to half of the input voltage. At any instant (n-1) switches are conducting, which is far less than conventional MLI. All the switches are operated at the lower frequency result in lower switching losses. The experimental setup is developed based on simulation parameters and it is observed that both results are closely identical.
