Abstract

This paper proposes a single-phase fifteen-level inverter using seven switches, with a novel pulse width-modulated (PWM) control scheme. The Proposed multilevel inverter output voltage level increasing by using less number of switches driven by the multicarrier modulation techniques. The inverter is capable of producing fifteen levels of output-voltage (Vdc, 6Vdc/7, 5Vdc/7, 4Vdc/7, 3Vdc/7, 2Vdc/7, Vdc/7,0, -Vdc/7,  -2Vdc/7, -3Vdc/7, - 4Vdc/7, -5Vdc/7, -6Vdc/7, -Vdc) from the dc supply voltage. A digital multi carrier PWM algorithm was implemented in a Spartan 3E FPGA. The proposed system was verified through simulation and implemented in a prototype.
