Abstract
This paper presents analysis and operation of a cascade multilevel inverter for three
phase
induction motor drives using an optimized stepped-waveform harmonic elimination technique which
provides balanced source power transfer. The objective of this technique is to offer similarly useful life
time of each dc supply of the H-bridge inverter. This paper gives detail of switching angle calculation
based on a Newton-Raphson method. Simulation using
MATLAB/SIMULINK program is also
included.
Additionally, testing of the prototype for verifying operation compared with simulation was conducted.
The result appears satisfactory.
