Multilevel regular-based binary multiplier for SPIM speed control

This paper presents multilevel regular-based binary multiplier switching method and parallel-full bridge inverter circuit for controlling speed of single-phase induction motor (SPIM). By constructing various types of 8 bit regular-based binary multiplier signal (RBM) modulated by single-phase multilevel signal, and then generating inverter output signal. This technique can improve the inverter output signal´s performance, which demonstrates in term of reduction of total harmonic distortion (THD) and lower-order harmonic when applying to control the motor, resulting to improve the motor efficiency and performance.
