For the integration of green energy, this paper suggests a novel multilevel inverter architecture with a simple switch topology. It makes use of 14 switches and 4 DC sources. By selecting the DC sources of equal magnitude, nine levels of output can be obtained and by choosing the voltage ratio as 1:2:7:14, 49 levels of output voltage are obtained. Switching pulses are produced using the multicarrier pulse width modulation technique. Logic gates are used to implement the switching scheme and to generate the pulses for the switching operation. With a 49-level multilevel inverter, the total harmonic distortion value is found to be 1.76%. The issue of capacitor voltage balancing is totally resolved because there are no capacitors. MATLAB simulations are done for both nine and forty-nine levels for a pure resistive load. The hardware implementation of the simulated circuit is under process.

摘要

For the integration of green energy, this paper suggests a novel multilevel inverter architecture with a simple switch topology. It makes use of 14 switches and 4 DC sources. By selecting the DC sources of equal magnitude, nine levels of output can be obtained and by choosing the voltage ratio as 1:2:7:14, 49 levels of output voltage are obtained. Switching pulses are produced using the multicarrier pulse width modulation technique. Logic gates are used to implement the switching scheme and to generate the pulses for the switching operation. With a 49-level multilevel inverter, the total harmonic distortion value is found to be 1.76%. The issue of capacitor voltage balancing is totally resolved because there are no capacitors. MATLAB simulations are done for both nine and forty-nine levels for a pure resistive load. The hardware implementation of the simulated circuit is under process.
