Generalized PWM Control of Dual Inverter Fed Induction Motor Drive
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 1
Abstract
A simplified generalized pulse width modulation (GPWM) algorithm is proposed to obtain various continuous and discontinuous PWM algorithms for a four level inverter topology. Induction motor both sides are fed with a three-level inverter from one side and a two-level inverter from the other side. The proposed configuration is capable to produce an output voltage of two-level, three-level and four-level in entire modulation range. Neutral clamping diodes and neutral point fluctuations are absent in the proposed inverter topology. In the proposed inverter topology the switching losses are reduced with the application of various discontinuous PWM algorithms compared with continuous PWM algorithms. Simulation analyses are carried out in MATLAB/SIMULINK environment and the results are presented.
